The maths

A slab your buyer can check is worth more than your word.

On a live stream, condition is the buyer's biggest doubt. A measured grade in a tamper-evident slab - with a QR cert they can scan on screen while you're selling - removes it. It gives buyers something to check, not just your word.

Slabbed · buyer-verifiable

Same card, more confidence. Buyers can verify the grade in seconds - no "trust me on the corners".

Built for the way you sell

Whatnot and eBay - same slab, two edges.

Whatnot lives

Slab your hits before you go live and sell them graded, not raw.

  • Buyers scan the QR and verify the grade on screen, mid-auction
  • A measured grade beats "looks mint to me" in a fast room
  • Back within 7 days of arriving keeps your inventory moving

eBay Live & listings

A verified grade in the listing does two jobs at once.

  • Buyers can check the grade before they bid
  • The grade is on record, with the measurements behind it
  • No transatlantic shipping, no customs, no weeks in transit
Why the grade holds up
±
Measured, not guessed

Scored by machine against the same standards - then checked by hand to make sure it's genuine.

▤
Every number shown

Centering, corners, edges, surface - all on the record with the image behind them.

◉
Public registry

Every card we grade is listed and QR-verifiable - your buyer checks it in seconds.

⊘
Tamper-evident slab

Serialised and sealed, so you'd see if anyone opened it - and the QR shows the real grade.
