Pokemon Seals: Repacks, Slabs, ETB Cases and Break Shipments

Build your Pokemon seals

Pokemon repack seals, pokemon slab stickers and pokemon mystery pack seals all do one small, boring job: they put your brand and a number on the outside of a piece of plastic, so what left your table can be photographed, logged and matched against what comes back. The seal is a die-cut holographic foil label, 1.77 x 0.75 in (44.96 x 19.05 mm) in the standard size. It goes on the acrylic, the toploader, the bag flap or the mailer seam — never on a card, never on factory wax.

Custom pokemon card packaging stickers are cheap enough to put on every unit: $6.00 per pack of 12, 60-seal minimum at $30.00. Used honestly, a numbered seal helps deter swaps and return fraud — the buyer can see, before they open anything, that the outside was numbered and photographed.

Never on the wax. Ever.

This is the one rule that does not bend. A seal never goes on a booster pack, a booster box, a bundle, an ETB, a tin, or any factory shrink wrap. Sealed Pokemon product is worth what it is worth because the wrap is untouched by anyone but the manufacturer. A foil label on that wrap — even yours — makes the item look worked on and earns you a return you deserve.

The seal goes on the secondary plastic instead: the acrylic display case around the ETB, the toploader, the one-touch magnetic holder, the graded slab, the team bag, or the shipping box. Same photo, same number, same log — the wax stays as it left the factory. See sealed wax boxes and packs.

Four Pokemon formats and where the seal goes

1. Graded slabs — pokemon slab stickers

PSA, CGC, BGS and SGC slabs take the slab banner layout: a long, narrow seal across the back of the case, low, below the grader's own label so nothing on the front is covered. The LARGE size, 2.5 x 1 in (63.5 x 25.4 mm), spans more of the back if you want the number readable in listing photos. One rule beyond the wax rule: do not seal a slab going out for a crossover or a regrade. Walkthrough: how to seal a graded slab.

2. ETB acrylic cases — the pokemon etb case sticker

Elite Trainer Boxes get displayed in fitted acrylic cases, and that acrylic is the correct surface. Put a flat seal on the lower front corner, or a folded layout over the lid seam so the number sits across the opening and reads in your packing photo. The ETB inside never touches adhesive. Number a display shelf in a run — ETB-001 upward — and inventory photos become a numbered set, not twelve identical boxes.

3. Mystery packs and repacks — pokemon mystery pack seals

A repack is opaque by design, so the number is the only thing you and the buyer agree on before it opens. Build the pack, run the seal across the flap or closure, then photograph the unit with the number legible. Within one order, no two seals share a number, so when someone messages about pack MYS-0148 you open the photo of MYS-0148. See pokemon mystery pack seals.

4. Break shipments

Breakers ship stacks: hits from one slot, penny-sleeved, into 35pt and 55pt toploaders, banded into a team bag, into a bubble mailer. Two placements work — a toploader banner on each holder for per-card numbering, or one seal across the bag flap and one across the mailer seam to document the shipment as a unit. Note the number against the buyer's username as you pack: how to seal a break stack.

What a seal will not do

Say this in your listings too. A seal can be peeled off and replaced by anyone with patience and a hair dryer. It is a printed holographic foil label, not a lock. It says nothing about the card inside — not the grade, not the condition, not whether a pull is real. It has no standing with eBay, Whatnot, TikTok Shop, PSA, CGC, BGS or SGC; none of them treat one specially. It does not decide a return.

What it does is narrower: it gives the unit a number, and gives you a photo and a dated log entry tied to that number. That helps document what was shipped. Any wording you hand a buyer should describe only those three things — the number, the photo and the log.

Pokemon collection numbering, slab by slab

Pokemon collection numbering is shelf discipline with a foil label on top. Pick a prefix that means something — set code, era, or your handle — set a start number, and run sequentially: BS-001, BS-002, onward. Apply a slab banner as you number each case, photograph the back, and note the grader's own label number beside yours in a spreadsheet. The collection then has one index you control: number your Pokemon slab collection.

You do not have to number at all. The builder offers your prefix plus sequential numbering from a start number you set, random codes, a batch code plus a number, or no number. Add an optional QR pointing at a page you choose, or at the seal record — a page showing the design, the number and the date it was logged. It says nothing about the card. Your run stays private in My Seals.

Designs, foils and layouts

Two holographic foils: Shattered Prism, a hard fractured shimmer that photographs loud, and Aurora, a smoother spectral sweep. Both take your own artwork — logo, shop name, mascot. Layouts: portrait and landscape flat, folded portrait and landscape for wrapping a seam, slab banner, toploader banner, and Duo, two numbered halves on one label that you cut apart.

Custom Grading Stickers are a separate product for toploaders and slabs: five layouts, ten holographic backgrounds, your own displayed grade, packs of 12 at $6.00 (50c each) down to 40c each at 600+. They carry the mandated line: Custom collector display sticker. Not affiliated with or certified by any third-party grading company.

Questions from Pokemon sellers

Can I put a seal on a sealed ETB or booster box?

No. Never on the wax. Adhesive on factory shrink wrap ruins the item for the sealed market. Put the seal on the acrylic display case around the ETB, or on the shipping box.

Where exactly does the seal go on a graded slab?

Across the back of the case, low, below the grader's own label, using the slab banner layout. Never on the front over the card window, and never on a slab heading back to a grading company for a crossover or a regrade.

How do I number a repack or mystery pack series?

Set a prefix and a start number in the builder and run sequentially, for example MYS-0001 upward. Photograph each sealed unit with the number legible before it ships, and note the number against the order. Within one order, no two seals share a number.

What does the QR code show?

A page showing the design, the number and the date it was logged. It says nothing about the card, the grade or the contents. You can also point the QR at any page you choose, such as your shop or your break schedule.
