Frequently Asked Questions
What is an Armalope?
An Armalope is a trading card shipping envelope built for sports cards, Pokémon cards, and other trading cards. Its built-in pocket holds a toploader or semi-rigid holder in place to help reduce movement during shipping.
For eBay Standard Envelope, the Armalope is the best way to ship trading cards and superior to the standard PWE setup. It gives the card a more secure fit without the extra tape, paper, or makeshift inserts people usually use. Pair it with Easy Glide penny sleeves and the right rigid holder for a faster, cleaner way to ship cards on eBay.

How does the Armalope work?
Three steps: (1) Sleeve your card with an Easy Glide Soft Sleeve and load it into a toploader or semi-rigid holder. We also recommend masking/painters tape seal the holder shut to preven the card from sliding out during transit (2) Slide the holdered card into the Armalope's built-in pocket. (3) Peel the adhesive strip and seal. That's it. The pocket creates tension around the card holder so nothing shifts during sorting, transport, or delivery. Read the full step-by-step: How to Ship Trading Cards.
What types of Armalopes are available?
Four Armalope types cover every shipping scenario: Single Pocket — fits one toploader or semi-rigid, weighs 0.45 oz, perfect for eBay Standard Envelope. Double Pocket — fits two semi-rigids or two stacks under ¼", still eBay Standard Envelope compliant. Heavy Stock — thicker construction for toploaders, relics, and premium stock that ships non-machinable. Parcel Mailer — 360° rigid protection for graded slabs, one-touches, and card stacks shipped via parcel.
What fits inside an Armalope?
For eBay Standard Envelope and other letter-mail shipments, the USPS limit is up to 1/4" total thickness and up to 3 oz total weight for the entire package. That includes the card, sleeve, holder, and Armalope. So an Armalope fits standard trading cards stacked within those limits, not a fixed number of cards or holders in every case. The double pocket envelope can hold twice as many cards while still not hitting the 1/4" limit. Always sleeve your card with Easy Glide sleeves and load into a holder before placing in the Armalope.
The Armalope Parcel Mailer fits PSA slabs, BGS slabs, SGC slabs, CGC slabs, one-touch holders, and thicker stacks of toploaded cards.
Are Armalopes reusable?
No — Armalopes are designed as single-use shipping envelopes. The adhesive seal is a one-time peel-and-stick closure that creates a tamper-evident seal.
What is eBay Standard Envelope?
eBay Standard Envelope is USPS's cheapest shipping option for flat, lightweight items like trading cards. It's available for items sold under $20 on eBay. Requirements: the envelope must be flexible enough to pass through USPS sorting machines (machinable) or marked as non-machinable, weigh under 3 oz, and be under ¼" thick. It's significantly cheaper than parcel shipping — which is why every serious eBay card seller uses it for low-value sales. Armalopes are specifically engineered to meet these specifications. Full eBay shipping guide.
Are Armalopes eBay Standard Envelope compliant?
Yes. The Single Pocket and Double Pocket Armalopes are designed specifically for eBay Standard Envelope service. The Single Pocket weighs just 0.45 oz — well under the 1 oz machinable limit with a card and semi-rigid inside. The Double Pocket stays under 3 oz with two cards. Both meet USPS dimensional requirements for standard envelope mail. The Heavy Stock version ships as non-machinable eBay Standard Envelope (still cheap, slightly more than machinable).
What's the difference between machinable and non-machinable mail?
Machinable mail is flexible enough to pass through USPS automated sorting machines — this is the cheapest rate. Semi-rigid holders inside a standard Armalope qualify as machinable because they flex slightly. Non-machinable mail contains rigid items (like toploaders) that can't bend through sorting equipment — it costs slightly more but is still eBay Standard Envelope pricing. Mark the envelope "Non-Machinable" and select the 3 oz rate on eBay. Use the Heavy Stock Armalope for non-machinable shipments. Detailed eBay shipping breakdown.
Which Armalope should I use for eBay Standard Envelope?
Quick guide: Single card in a semi-rigid → Single Pocket (machinable, cheapest rate). Two cards in semi-rigids → Double Pocket (machinable). Single card in a toploader → Single Pocket (non-machinable, mark envelope). Thick card/relic in toploader → Heavy Stock (non-machinable). Graded slabs or high-value cards → Parcel Mailer (ships via USPS Ground Advantage, not Standard Envelope).
Can I ship toploaders via eBay Standard Envelope?
Yes, but as generally as non-machinable mail. Most toploaders are too rigid for USPS sorting machines, so the envelope can get kicked out hand-sorted instead which risks shipping delays and damage. This costs slightly more than machinable rate but is still significantly cheaper than parcel shipping. Use a standard Single Pocket Armalope or Heavy Stock Armalope, select the 3 oz weight option on eBay, and write "Non-Machinable" on the envelope. For the absolute cheapest per-shipment cost, use semi-rigid holders instead — they flex enough for machinable sorting.
Single Pocket vs Double Pocket — which one do I need?
Single Pocket is your everyday workhorse for shipping card(s) up to the USPS limit of 1/4". It is the lightest weight (0.45 oz), cheapest shipping rate on Ebay and good for most of your eBay Standard Envelope shipments. Double Pocket lets you ship twice as many cards in one envelope before you hit the 1/4: limit allowing you combine more orders/card in the same shipment. Both types meet eBay Standard Envelope specs.
When do I need the Heavy Stock Armalope?
Use the Heavy Stock Armalope when shipping rigid or thick items that need extra envelope durability: toploaded patch/relic cards, thick memorabilia in 100PT+ toploaders, premium stock cards, or any shipment where the standard Armalope material feels too thin for the contents. Heavy Stock construction provides more rigidity around the card holder. Ships as non-machinable eBay Standard Envelope — still far cheaper than parcel rates.
When do I need the Parcel Mailer?
Use the Armalope Parcel Mailer for: graded slabs (PSA, BGS, SGC, CGC), one-touch magnetic holders, stacks of toploaded cards, or any raw card worth over $20 that justifies tracked parcel shipping. The Parcel Mailer provides 360° rigid protection — not just a pocket, but a full wrap that protects all sides. Ships via USPS Ground Advantage (or equivalent) with tracking and insurance options. This is your high-value shipping solution when eBay Standard Envelope isn't appropriate.
What are the Armalope bundles?
Two complete shipping kits: The Toploader 100CT Bundle includes Armalopes + toploaders + Easy Glide sleeves — everything you need to sleeve, topload, and ship 100 cards. The Semi-Rigid 200CT Bundle includes Armalopes + semi-rigid holders + Easy Glide sleeves for 200 machinable-rate shipments. Bundles are the most cost-effective way to stock your full shipping pipeline. Shellz Club members get additional bulk discounts on bundles.
How do I package a trading card for shipping?
Three steps: (1) Sleeve your card with an Easy Glide Soft Sleeve and load it into a toploader or semi-rigid holder. We also recommend masking/painters tape seal the holder shut to preven the card from sliding out during transit (2) Slide the holdered card into the Armalope's built-in pocket. (3) Peel the adhesive strip and seal. That's it. The pocket creates tension around the card holder so nothing shifts during sorting, transport, or delivery. Read the full step-by-step: How to Ship Trading Cards.
How do I prevent cards from getting damaged in shipping?
Card shipping damage comes from three sources: surface scratches (prevented by penny sleeves), bending and corner damage (prevented by toploaders or semi-rigid holders), and movement inside the envelope (prevented by Armalope's built-in pockets). All three layers work together. A card loose in a PWE fails on all three counts. A sleeved card in a toploader loose in a PWE still fails on movement — the toploader slides around and corners get dinged against the envelope edges. Armalopes solve the movement problem that DIY setups can't reliably fix.
Armalope vs plain white envelope (PWE) — what's the difference?
A plain white envelope is just an envelope. You have to create your own card protection inside it — lined paper, painter's tape, cardboard stiffeners, rubber bands, hope. It's time-consuming, inconsistent, and looks unprofessional to the buyer. An Armalope has built-in pockets engineered to hold toploaders and semi-rigids securely. No movement, no rattling, no DIY. The time savings, damage prevention, and buyer impression are well worth the extra cost compared to a PWE.
Can I ship graded slabs in an Armalope?
Yes — use the Armalope Parcel Mailer. It's specifically designed for graded card slabs from PSA, BGS, SGC, and CGC. The Parcel Mailer wraps around the slab with 360° rigid protection — all six sides are covered. Ship via USPS Ground Advantage (or equivalent tracked service) with insurance for the card's value. Do not ship graded slabs via eBay Standard Envelope — slabs are too thick, too rigid, and too valuable for envelope shipping. The Parcel Mailer is your slab-shipping solution. For raw high-value cards ($20+), the Parcel Mailer is also recommended over Standard Envelope for the added tracking and insurance.
How do I ship sports cards and Pokémon cards on eBay?
Same process for all card types — sports, Pokémon, MTG, Yu-Gi-Oh!, any TCG: (1) Easy Glide sleeve → (2) semi-rigid or toploader → (3) Armalope. For items under $20, use eBay Standard Envelope. For items over $20 or graded cards, use the Parcel Mailer with tracked shipping. The card type doesn't change the process — the value determines the shipping method. A $5 Pokémon card and a $5 baseball card get the same protection. A $200 card gets the Parcel Mailer regardless of sport or game. Detailed eBay shipping guide.
Trading Card Shipping Envelopes — The Armalope by Card Shellz
Shipping trading cards shouldn't require an arts and crafts session. Lined paper, painter's tape, cardboard stiffeners, rubber bands around a toploader jammed into a plain white envelope — that's not a shipping method, it's a field expedient. The Armalope is Card Shellz's purpose-built card shipping envelope with integrated pockets that hold your toploader or semi-rigid holder securely from drop-off to delivery.
Every Armalope features a built-in pocket that creates tension around your card holder — zero movement, zero rattle, zero corner dings from the card sliding around inside the envelope. Drop in your sleeved, holdered card, peel the adhesive strip, and seal. Three steps. No tape. No cardboard. No crossed fingers. The Single Pocket weighs just 0.45 oz — well under the cheapest eBay Standard Envelope rate with a card inside.
Available in four configurations: Single Pocket for everyday one-card shipments, Double Pocket for two-card orders, Heavy Stock for thick toploaders and relics, and Parcel Mailer for graded slabs and high-value cards. Pair with Easy Glide penny sleeves and toploaders for the complete protection-to-shipping pipeline.

How to Ship Trading Cards on eBay — eBay Standard Envelope Guide
eBay Standard Envelope is the most cost-effective way to ship trading cards sold under $20. It uses USPS letter mail rates instead of parcel rates — saving sellers dollars per shipment that add up fast at volume. But Standard Envelope has rules: the envelope must be under ¼" thick, under 3 oz, and either flexible enough for machine sorting (machinable) or marked as non-machinable for hand-sorting at a slightly higher rate.
Armalopes are engineered for eBay Standard Envelope compliance. The Single Pocket with a semi-rigid holder inside qualifies as machinable mail — the cheapest possible rate. With a toploader inside, it ships as non-machinable (still Standard Envelope pricing, just marginally more). The Double Pocket lets you combine two cards into one shipment while staying within Standard Envelope specifications.
For cards over $20 or graded slabs, skip Standard Envelope entirely — use the Armalope Parcel Mailer with USPS Ground Advantage for tracking and insurance. The value of the card determines your shipping method, not the card type. Protect every shipment the same way: Easy Glide sleeve → holder → Armalope → ship. Read the step-by-step process: How to Ship Trading Cards on eBay.
Which Armalope Do You Need? — Complete Card Shipping Guide by Card Type
Choosing the right Armalope depends on what you're shipping and how you're shipping it. Here's the decision matrix:
Single standard card (under $20) — Easy Glide sleeve + semi-rigid holder + Single Pocket Armalope. Ships machinable eBay Standard Envelope. Cheapest option. Two standard cards (under $20) — Two sleeved cards in semi-rigids + Double Pocket Armalope. Machinable, one label, one shipment. Single toploaded card — Sleeve + toploader + Single Pocket Armalope. Non-machinable Standard Envelope (mark envelope, select 3 oz on eBay).
Thick relic/patch card in toploader — Sleeve + thick toploader + Heavy Stock Armalope. Non-machinable. Graded slab (PSA/BGS/SGC/CGC) — Parcel Mailer. Ship USPS Ground Advantage with tracking + insurance. High-value raw card ($20+) — Parcel Mailer recommended for tracking and insurance coverage.

Armalope vs Plain White Envelope (PWE) — Why Professional eBay Sellers Switched
Every eBay card seller starts with plain white envelopes. Wrap the toploader in a piece of lined paper, tape it shut, stuff it in an envelope, tape the envelope closed, write "Do Not Bend" on the outside, and hope the postal sorting machines don't destroy it. It works — until it doesn't. And when it doesn't, you're refunding the buyer, eating the shipping cost, and getting a negative review that tanks your seller rating.
The Armalope eliminates every failure point in the PWE method. Built-in pockets hold the card holder rigid — no movement, no corner dings from sliding around inside the envelope. Proper adhesive sealing — no tape failures, no envelopes popping open in transit. Professional appearance — your buyer opens a purpose-built card mailer, not a homework envelope held together with Scotch tape. The cost difference is pennies per shipment. The difference in buyer experience and damage prevention is massive.
Professional eBay sellers shipping 50+ cards per week switched to Armalopes because the math is simple: one damaged-in-transit card costs more in refunds and reputation damage than a year's supply of Armalopes. Time savings compound too — three-step Armalope packing vs. five-minute PWE arts and crafts projects per card. At volume, that's hours per week recovered. Shellz Club bulk pricing makes Armalopes the obvious choice for any seller who's serious about scaling their card business. Full shipping guide | eBay-specific shipping guide.
