How to ship trading cards safely
Follow a simple, repeatable process to protect cards during transit. This guide covers inspection, packing materials, step-by-step packing, documentation, and final checks so your baseball, basketball, football, hockey or soccer trading cards arrive in the same condition a collector expects.

Before you pack
Inspect each card for existing wear, edge dings, creases, or surface marks. Record the card identifier (team, player, set, and serial number if present) and its visible grade or PSA slab grade. Scan or photograph front and back at high resolution and save the images with the identifier in the filename. Note whether the card is intended for trading or sale so you can include the right paperwork. If a buyer or collector requests a specific grade, attach that notation to your records but avoid writing on the card or sleeve.
Materials you'll need
Gather these items: penny sleeves, a 130pt top loader, tape, a sheet of rigid cardboard for bracing, a Bubble mailer sized to avoid shifting, scissors or a cutter, and a camera or phone for scans. For slabbed PSA cards use extra stiff bracing and a larger mailer. Keep an inventory list with identifiers and photos handy for each shipment.
Packing step-by-step
1) Slide the card into a penny sleeve. 2) Place the sleeved card into a 130pt top loader; ensure the card sits flat and cannot slide out. 3) Tape the open end of the top loader with a short strip of tape that does not touch the card surface. 4) Sandwich the top loader between two pieces of rigid cardboard cut slightly smaller than the mailer and tape the cardboard edges together to form a stiff cradle. 5) Put the cradle into a Bubble mailer with the tape-sealed end away from the opening seam. 6) Fill any extra space with a small piece of bubble wrap to prevent movement. 7) Seal the Bubble mailer securely and add external tape on the flap. For multiple cards, stack each card in its own top loader and separate them with cardboard to prevent rubbing; do not place cards back-to-back without padding.
Labeling and documentation
Write the recipient address clearly on the package carrier label; do not write on the top loader or directly on the card sleeve. Include a printed packing slip with the list of identifiers and scans attached or uploaded to your order record. Note the declared contents generically as 'collectible cards' if required for customs, but keep your internal list with full identifiers and grade information. Photograph the sealed package and save the scan of the shipping label before drop-off to document condition at shipment.
Final checks and a single tool to help
Before handing the package to the carrier, shake it gently to confirm there is no internal movement, confirm the Bubble mailer is sealed, and verify tracking has been created. If you need a way to share identifiers, scans, and grade notes with a buyer or to manage many shipments, Slabbr can help organize photos and order identifiers in one place.
Common questions
- Can I ship a single card in a standard envelope?
- A standard envelope offers little protection against bending or crushing. Use a 130pt top loader inside a Bubble mailer or a small box with rigid bracing to prevent edge damage and shifting.
- How should I pack a PSA slabbed card?
- Leave the card in its PSA slab. Place the slab in a stiff 130pt top loader or between rigid cardboard sheets, tape the cardboard edges, and place that assembly into a Bubble mailer. Ensure the slab cannot move inside the package and add extra padding to corners.
- Do I need to scan my cards before shipping?
- Yes. Make a high-resolution scan or photo of front and back and save it with the card identifier; include those files in your order record. Scans document condition and the identifier against disputes over grade or damage.
