How to Ship Trading Cards Safely
5 minute read · Updated July 2026
A trading card can survive decades in a binder and die in two days in the mail. Almost every shipping disaster comes down to one of three causes: the card could move inside the package, the package could bend, or there was no tracking when something went wrong. All three are cheap to prevent.
Here is the packaging standard used by careful sellers everywhere, and by every order shipped from this site.
The four-layer standard for raw cards
First, a penny sleeve: the thin soft sleeve that protects the surface from scratches. Slide the card in top first and never force it.
Second, a toploader or semi-rigid holder. A toploader is the rigid plastic case that prevents bending. Semi-rigid holders such as Card Savers hold the card more snugly and are what most graders ask for in submissions.
Third, a team bag: the resealable plastic sleeve that wraps the toploader so the card cannot slide out and dust cannot get in. Painter's tape over the toploader opening works too, but never let tape touch the card or sleeve directly.
Fourth, a bubble mailer with the cards held between the bubble padding, ideally sandwiched with a piece of rigid cardboard on each side. Write or print the address clearly and keep the package flat.
- Penny sleeve protects the surface
- Toploader or Card Saver prevents bending
- Team bag keeps the card from sliding out
- Padded mailer with cardboard stiffeners survives the sorting machines
Shipping graded slabs
Slabs are tough but not indestructible, and a cracked slab means an expensive regrade. Wrap each slab in a layer of bubble wrap, tape the wrap to itself, and pack it snugly in a bubble mailer or small box so it cannot rattle. For multiple slabs, wrap each one separately so they cannot knock against each other in transit.
Always use tracking
A plain white envelope with a loose card and a single stamp is how cards get bent, lost, and disputed. Tracked first-class packages cost a few dollars, give both sides proof of delivery, and are the only sane way to ship anything you care about. For high-value cards, add insurance and signature confirmation.
