Die-cut 0.75" × 1.77" seals printed in full color on holographic vinyl, made for the trading-card world: wrap a graded slab's seam, seal a box flap, close a break stack, number an edition. Each seal carries your brand and its own serial number.

The standard die is 1.77" × 0.75", and the builder lays it out six ways: flat portrait or landscape, folded portrait or landscape for wrapping a seam, a slab banner for a graded slab's top edge, and a toploader banner for a toploader's opening. Same seal, same numbering — the shape just matches where it's going.

A larger 2.5" × 1" seal is available now — pick Large in the builder. Every layout comes in both sizes; Large prints on either foil in packs of twelve at $9.00 a pack. Large has its own volume ladder — 10% off at 120 seals, 20% at 600, 30% at 1,200 and 40% at 4,200 (45¢ a seal, the Large floor).

Not in one piece. It's thin holographic vinyl on permanent adhesive: it grips, and it tears and distorts on the way off rather than lifting cleanly. That's what the material is — we're describing the stock, not promising you what it stops.

It is still film on adhesive. One seal can be taken off, and a different one can be put on in its place. What a Serial Seal™ has that a blank sticker doesn't is the number: you chose it, we printed it, and you can write it down.

Two silver holographic stocks, both with permanent adhesive, printed on commercial resin-ink presses: Shattered Prism, a bold fractured-glass sparkle, and Aurora, a smoother wash of drifting color. You pick the stock in the builder. Unprinted areas show the rainbow holo shine — the designs use that as a feature — and QR-heavy designs print the code on a white patch for scan contrast.

Yes. The ghosted diagonal watermark you see in the preview is printed on every seal — along with the serial microtext and the engraved rosette. It is not a preview overlay and it is never removed. Detail that fine is the part a home printer or a colour copier can't hold.

Yes — designs with a logo slot take a transparent-background PNG. JPEGs and white-background images print an ugly solid box over the holo shine, so the builder only accepts PNG.

Every seal gets its own number, in a scheme you choose. You pick the prefix — ACME- — and then how the run is numbered: sequential from a starting number you set (ACME-001, ACME-002 …), random codes after the prefix, or a batch code plus a number. Within a single order, no two seals ever carry the same number. Numbers are unique across your order, not a global register — we don't claim a number is unique across every order we have ever printed.

Which scheme? A sequence reads like a print run and lets you continue a series on the next order; a random code tells a stranger nothing about how big your run is. Random is the default in the builder; sequential is one tap away.

Numbering is optional. Plenty of shops order these as plain branded vendor stickers with no number at all — same seal, same material, same artwork, just without the number.

The number is the part you can write down. One seal, one number, one item — so a seal you photographed ties that item to that sale in your own records.

It's optional, and it goes straight to whatever web address you choose — your shop, your listing, your break page, your socials. Scanning it opens your link directly; nothing is routed through us and nothing is looked up on our site. Links are capped at 60 characters because longer codes won't scan reliably at seal size — use a short link.

A standard code can't change — your link is printed in the foil. If you want a destination you can move later, SerialSeal Business prints a short link we host (s.serialseal.com/…) and where it sends people is a setting you can change afterwards, for ever, without reprinting a seal.

Business is $359.88 billed for 12 months ($29.99/month equivalent), belongs to your account rather than to one order — so every future run reuses the same plan — and is offered in the builder when you pick the QR.

No. The same link prints on every seal in the run. We don't encode the seal's number into the code, we don't generate a different code for each seal, and we don't count or record scans. The number printed beside the code is what makes each seal unique — the code is just a shortcut to wherever you want people to land.

If you need each sticker to lead somewhere different, that lives on your side: point every seal at one page you control, and use the printed numbering to tell the items apart.

No. We print and number seals — we don't run a public registry, and nothing about your order is looked up on our website. It stays in your hands: a numbered seal on the item, plus your own photos and records. Nothing you rely on depends on our site being up.

60 Serial Seals™ minimum · From $30.00 · As low as $0.30 each in bulk (Standard size). Seals print in twelves, so a run lands on a whole twelve: twelve is $6.00 at the list rate, and the smallest order is 60 seals for $30.00. No setup, die, or design fees, and a commercial license and copyright are included in the price.

The per-seal price falls as the run grows: 120 seals is 45¢ each ($54.00) — 10% off — and 600 seals is 40¢ ($240.00) — 20% off. Past that the deep rungs keep falling: 1,200 seals at 36¢, 2,400 seals at 33¢, and 4,200 seals at 30¢ ($1,260.00) — 40% off the list rate. 30¢ is the Standard floor, and it holds for every run above 4,200 seals. The Large size runs its own ladder off $9.00 a pack and bottoms out at 45¢.

The tier comes off automatically at checkout, so there is nothing to enter and nothing to ask for. Only one tier applies at a time, and discount codes don't stack on top of it. 10,008 seals is the largest run the builder takes in one go — for more than that, tell us what you're sealing.

That is a production conversation rather than a checkout — stock, press time and lead time all come into it — so ask us for a quote and we will price the run for you.

No — collectors and card-show vendors use the same seals inward. Serialize your own inventory: every slab, team bag, and storage box gets its own number, so you can count a case at a glance, track what's in storage, and match the number when something you loaned, traded, or displayed comes back.

It gives you a record, which is the thing sellers usually lack. The common problem on eBay, Whatnot and TCGplayer is a buyer receiving a high-value card and returning a swapped or damaged one under a “not as described” case.

Seal the slab before it ships, photograph the seal, and note the number against the order. If what comes back carries a different number — or no seal at all — you're pointing at a dated photograph rather than recalling what you packed.

To be straight with you: marketplaces decide their own cases and no seal — ours included — forces an outcome. The seal isn't doing the work here — your record is. What changes is that you arrive at the dispute with a photograph and a number instead of a description from memory.

It's a notice, not a mechanism — the same line you'd read on a warranty sticker. It states the condition you're selling under. The seal doesn't enforce it and doesn't decide anything.

The part that does the work is your own record: photograph the seal on the item before it ships and note the number against the order.

Orders print same or next business day and ship as soon as they're done.

No — all sales are final. Every order prints with your brand text and your numbering on it, so it is a run made for you and for nobody else. Production starts as soon as the order lands, often within minutes, which is why there is no window in between: we can't change the design, the artwork, the brand text, the numbering, the quantity, the material or the shipping address, and we can't cancel.

Check it before you submit. It's all on screen — the design, your brand text, your first number and the seal count in the builder, and the address at checkout. Up until you check out you can still edit or remove a line in your cart; after that the run is ours to print.

We fix that at our cost. Misprinted, defective or damaged seals, a run that doesn't match what your order said, or a parcel lost or damaged in transit — tell us within 14 days of delivery and send photos of the seals. We reprint and reship free, you send nothing back, and if a reprint isn't the right answer we refund instead. A reprint carries the same numbers as the order it replaces.

What isn't a defect: holo foil shifts colour with the light, so no photo will ever match the seal in your hand, and screen colour is not print colour. Low-resolution artwork prints soft — the builder warns you about that before you buy. Read the full policy.

It is a die-cut holographic foil label with a permanent adhesive, applied to the plastic of a holder, case, bag or box — never to the card itself. It is not shipping tape, and it peels back off the shell. Keep it off any holder that is headed to a grader, and off factory-sealed wax: put it on the acrylic case or the shipping box instead. The placement guides say where it goes on each format.

No. A seal goes on the holder, the case, the bag or the box — the plastic around the card, never the card. Adhesive on a card is damage, and no number is worth that.

Both fit. The Standard 1.77 × 0.75 in seal sits across the seam of a 35pt to 130pt magnetic case; the Large 2.5 × 1 in seal spans the seam with room for a logo and a number on one face, which is what most one-touch sellers use. See one-touch seals.

It peels off the plastic of a holder or case; a fresh label comes away in one piece, an old one may leave a little adhesive you lift with a fingernail or a drop of isopropyl. We make no repositioning promise — a seal is applied once, and a reprint carries the same numbers if you need to redo a run.

Count parcels, not cards: one seal per holder or package you ship. A seller sending 40 parcels a week uses about 160 a month, so 240 seals (20 packs, $108.00 at 45¢) covers six weeks; a breaker shipping 100 hits a week is in the 600 band (40¢, $240.00). Whatnot sellers has the arithmetic by cadence.

No. Anything on the case that a grading company did not put there is a reason for them to refuse or re-holder it. Seal a slab only when it is staying in your collection or shipping to a buyer, on the bottom edge clear of the label. Not affiliated with or certified by any third-party grading company.

Keep it open. Sequential numbering continues on your next order from any starting number you set, so a series like ACME-001 … ACME-240 picks up at ACME-241 whenever you reorder. Random and batch schemes have nothing to continue; plain seals have no number at all.

Nothing changes. The seal record behind a QR keeps showing the design, the number and the date it was logged, and My Seals keeps your past orders and proofs. A record shows what was logged — it says nothing about the card.
