The short answer
Sleeve, semi-rigid, cardboard sandwich in packing-slip order, loose rubber bands, padded sturdy box
CGC's own instructions are short and worth following literally. Every card goes into a protective sleeve, then into a semi-rigid sleeve CGC says "must be sturdy enough to allow us to remove the card safely". The stack goes between two pieces of cardboard larger than the cards, in the order the cards appear on the submission form packing slip, held with rubber bands that are firm but not tight. That bundle is padded, boxed, taped shut with the packing slips inside, and shipped — at your risk, since CGC states you are responsible for getting the cards to it safely.
To submit cards to CGC: create a free account, fill in the online submission form, sleeve each card and put it in a semi-rigid holder, stack the cards in packing-slip order between two oversized pieces of cardboard, band the bundle loosely, pad it, box it with the packing slips inside and ship it insured to CGC in Sarasota, Florida. Everything below is that sequence with the detail that stops it going wrong.
Two framing facts first. CGC states that "the shipping provider that you select when submitting your order refers to the return shipping from CGC Cards to you" and that "you are responsible for safely shipping your cards to CGC" — so the outbound leg, including insurance, is entirely on you. And CGC notes its packaging instructions are suggestions; the responsibility for secure packaging stays with the submitter.
Before you pack: the account and the form
CGC asks you to "create a free account using our quick and easy form". Paid membership is optional and starts at a published $39 a year, with CGC stating that Associate and Premium members save 10% on grading and Elite members save 20%. On anything above a couple of dozen cards at Bulk pricing, the discount outruns the membership fee, so decide this before you submit rather than after.
Then complete CGC's online submission form, which is where you declare each card and choose the service tier. The tier decision is a declared-value decision — pick the cheapest tier whose cap covers what the card is plausibly worth graded. The table is in CGC grading cost, and if you are heading for the $17 Bulk tier, read is CGC bulk worth it first, because it carries a 25-card minimum and a $500 cap.
Print the packing slip. It is not optional paperwork — the card order on it governs how you physically stack the cards, and the slips go in the box.
The packing sequence, as CGC publishes it
- Place each card into a protective sleeve. A standard soft penny sleeve, card face in, no tape.
- Place each sleeved card into a semi-rigid sleeve. CGC's wording is that the sleeve "must be sturdy enough to allow us to remove the card safely" — so a flimsy holder is a real rejection risk, and a toploader is the wrong tool because it is not designed to be opened.
- Stack all of the cards between two pieces of cardboard that are larger than the cards, and place them in the order in which they appear on the submission form packing slip.
- Secure the cardboard with rubber bands, firm enough to hold the sandwich together and stop cards sliding out, but not tight. CGC warns that cards packed too tightly may be damaged.
- Protect the bound bundle with packing material — CGC names bubble wrap, Styrofoam pellets or other shipping material.
- Pack it in a sturdy cardboard box, not packed too tightly, with the packing slips inside, then seal the outside completely with packing tape.
- If you paid for WalkThrough or Express, write WK or EX respectively on the outside of the box in large, bold letters.
- Ship to CGC Cards, 6802 Energy Court, Sarasota, FL 34240, United States — insured, with tracking, at your own risk.

1. Best semi-rigid for standard cards
Cardboard Gold Card Saver 1
Cardboard Gold · Standard modern cards going to PSA
The semi-rigid holder PSA's own shipping guide points you toward, at the size its instructions name. If you submit standard-thickness modern cards, this is the default and the decision is made.
Why it takes this slot: The format CGC's instruction describes: rigid enough for a grader to extract the card safely, thin enough that a few hundred of them still bundle flat between two boards.
- Holder size
- 3 5/16" x 4 7/8"
- Card thickness
- Standard cards up to roughly 20pt
- Material
- Acid-free, PVC-free rigid vinyl
- Common pack sizes
- 50, 100 and 200 count
What it does well
- Matches the semi-rigid dimensions PSA's shipping guide specifies
- Consistent fit from pack to pack, which matters when you are loading 200 cards
- Thin enough to band and ship in bulk without a bulky box
Where it falls short
- A snug fit — a thick or already-curved card needs care going in
- Priced above generic semi-rigids precisely because it is the submission standard
#ad We link to the listing rather than printing a price that would be wrong next week. How we are funded
2. The sleeve that goes inside it
Ultra Pro Platinum Soft Card Sleeves
Ultra Pro · The default penny sleeve
Clear, acid-free, consistently cut, and sold everywhere in 100-count packs. It is the sleeve every other sleeve gets compared to, and the one PSA's guidance effectively asks for: clear, not opaque.
Why it takes this slot: CGC asks for a protective sleeve first, then the semi-rigid. This is the default soft sleeve for that first layer.
- Size
- Standard 2 5/8" x 3 5/8" trading card
- Material
- Acid-free, PVC-free polypropylene
- Pack size
- 100 count, sold in multipacks
- Clarity
- Clear — grading-submission appropriate
What it does well
- Clear sleeve, which is what grading submissions require
- Consistent cut, so cards do not catch going in
- Cheap enough to sleeve a whole box without thinking about it
Where it falls short
- Thin by design — a sleeve is not protection on its own
- Static cling makes single-handed loading fiddly

3. Best way to build the sandwich
Hobby Armor Trading Card Shipping Protectors
Hobby Armor · The rigid sandwich inside the mailer
Two corrugated pads either side of the holder. This is the layer that stops a sorting machine bending the package, and it is the one most sellers skip.
Why it takes this slot: CGC wants the bundle between two pieces of cardboard larger than the cards. Purpose-made rigid protectors do that job more reliably than cut-up boxes.
- Material
- Corrugated cardboard
- Use
- One pad either side of a toploader or slab
- Sold in
- Size-specific packs for raw cards and for graded slabs
What it does well
- Corrugation resists bending across the flat face, which is the damage mailers do not stop
- Adds almost no weight, so it does not move you into a higher postage band
- Cut to card and slab footprints, so no trimming cardboard by hand
Where it falls short
- Stocked by hobby sellers rather than every big-box retailer
- Pointless on its own — it is a layer inside a padded mailer, not a mailer
#ad We link to the listing rather than printing a price that would be wrong next week. How we are funded
4. For a small submission
Duck Brand Kraft Bubble Mailers #0 (6x9)
Duck Brand · Graded slabs and small lots
The step up in size for anything in a slab. A PSA or SGC case will not fit a 4x8 mailer, and the #0 size is the smallest one that takes a slab plus padding.
Why it takes this slot: Above the 25-card Bulk minimum you are boxing. For a handful of cards on Economy or higher, a padded mailer around a properly built cardboard sandwich is the proportionate answer.
- Mailer size
- #0 — 6" x 9"
- Exterior
- Kraft paper with bubble lining
- Closure
- Self-seal adhesive strip
What it does well
- Fits a graded slab in a sleeve with padding on both faces
- Kraft paper is curbside-recyclable in more places than poly
- A mass-market brand, so restocking it is never a hunt
Where it falls short
- Kraft paper darkens and softens if it sits in a wet mailbox
- Oversized and wasteful for a single raw card

The two steps people get wrong
Packing-slip order. This is the instruction most often skipped and the one with the clearest downside. CGC asks for the cards in the sequence they appear on the slip so its intake can reconcile a bundle against your declaration without guessing. A shuffled stack of three hundred semi-rigids is somebody's afternoon, and it is the kind of friction that invites queries and delay.
Rubber band tension. The instinct is to make the bundle immovable, and CGC specifically warns against it: the bands should be "just tight enough to hold the cardboard pieces together and prevent the cards from falling out", because "if packed too tightly, the cards inside may get damaged". A band biting into the edge of a semi-rigid for 150 days of queue time is a real risk to the card you are paying to grade.
Screen before you pack, not after
Every card you pack costs the same fee whatever grade comes back, so the highest-value hour in this whole process is the one you spend deciding which cards go in. Look at centering with a tool rather than by eye, check all four corners under a bright light, and tilt the card to catch surface scratches that are invisible flat on. Anything with a crease is capped low on CGC's scale regardless of how good the rest of the card is — see CGC grading scale explained.
Photograph or scan the cards before they go, too. On a Bulk submission you will not see them again for roughly seven months, and a pre-submission image is the only record you have of the condition they left in. How to scan sports cards covers the method, and what cards are worth grading the selection decision.
Shipping the box
CGC does not prescribe a carrier, which means the choice and the risk are yours. Use a service with tracking and insurance to the declared value of the lot, keep the receipt, and do not write anything on the outside of the box that advertises what is inside beyond the WK or EX marking CGC asks for. A plain box is a safer box.
The supplies this whole sequence calls for — sleeves, semi-rigids, rigid boards, bands, mailers — are collected in best CGC submission supplies. The equivalent process for the other graders is in how to ship cards to PSA and how to package cards for PSA; the instructions are similar in shape and differ in detail, so do not assume one set covers the other.
When the slabs come back, the job changes from protecting cardboard to protecting plastic. Slabs scratch, and they are awkward to store loose — how to store graded cards and best slab storage boxes pick that up.
