Seal it. Number it. Prove it.

Tamper-revealing holographic seals for graded slabs, sealed product, and break stacks — every seal printed with its own unique serial number, so the item you sealed is provably the item you shipped. Designed seals, your logo, or full numbered runs.

№ 01

Designer seals

Pick from a gallery of card-culture designs — energy types, holo bursts, first-edition stamps — add your text, done. Full color on holo, not a plain sticker with a font on it.

Your logo

Breakers and card shops: upload a transparent logo and it drops into any seal layout. Every box you send out carries your mark — and shows if it was opened on the way.

Runs

The one nobody else does at this size: 100 to 1,000 seals, every single one uniquely numbered — your prefix, your starting number. Photograph the serial when you ship, and any swap or bogus return comes down to a photo, not an argument. Optional QR points at any link you choose.

The card you shipped is the card that comes back

Every seller on eBay, Whatnot or TCGplayer knows the move: a buyer receives a high-value card, returns a swapped, damaged or counterfeit one, and opens a "not as described" case. Without a way to identify the exact copy you sent, it becomes your word against theirs — and you usually lose.

Seal the slab before it ships and photograph the seal. Your serial is on it. If what comes back has no seal, a broken seal, or a different serial, it is not the item you sent — and you can show that with a photograph rather than an argument.

  • Your serial ties one specific card to one specific sale
  • The seal cannot be peeled and reapplied without showing it
  • Your artwork and your serial together — a generic seal or a wrong number is obvious at a glance
  • Works the same for sealed boxes, deck boxes and break stacks

Marketplaces make their own decisions and no seal forces an outcome. What this gives you is specific, dated, photographic evidence that the returned item is not the one you shipped — which is a far stronger position than describing the card from memory.

How it works
STEP 1Design in the browser

Live preview at true size. What you see is exactly what prints — same file, same renderer.

STEP 2We print & number

Commercial resin-ink presses on holographic die-cut stock. Serialized runs are numbered at print time — no two seals alike.

STEP 3Seal & photograph

Wrap the slab seam or box flap, then photograph the seal on the item before it ships. That serial in your photos ties this exact item to this exact sale.

Straight talk
“Tamper-revealing,” not magic. Our holographic vinyl distorts and shows damage when peeled — it makes opening obvious, and the unique serial makes substitution obvious. No sticker makes a package impossible to open, and we won't tell you otherwise. More in the FAQ →
