Short answer: never ship sealed product in a bag or in a box that only just fits. Wrap it, put it in a sturdy shipping box with about 2 inches of padding on every side, and ship it tracked (USPS Ground Advantage for most boxes). The label goes on the shipping box, never on the product.
What "sealed" means on TCGplayer
TCGplayer's page What qualifies as a sealed product? sets the standard. The item must be "In its original, unopened packaging", "Undamaged", with packaging that "shows no damage or wear and tear", seals "not broken", and "Not re-shrink-wrapped or re-sealed". A dented or torn box can fail that test, so the packing is part of the product.
The box-in-a-box method
- Leave the shrink wrap on. It's the proof the product is factory sealed. Don't add tape to the product.
- Wrap it in a layer of bubble wrap or kraft paper so the corners can't rub.
- Pick a box about 2 inches bigger on every side. A booster box in a box that only just fits takes every bump straight into its corners.
- Fill the gap with packing paper, air pillows or bubble wrap until nothing moves when you shake it.
- Tape the seams with packing tape (an H across the top and bottom), and put the label and slip on the outside box. For a case, the factory case goes inside a shipping box the same way.
Packs and small boxes (a single blister, a bundle) can go in a rigid mailer or a small box with padding; a bubble mailer alone lets the edges crush.
Which service
| What you're shipping | Service | Notes |
|---|---|---|
| Booster packs, small boxes | USPS Ground Advantage | Tracking included; not a stamped envelope |
| Booster box, ETB, bundle | USPS Ground Advantage | Includes tracking and up to $100 of insurance |
| Product worth more than $100 | Ground Advantage or Priority Mail + extra insurance | Insure the real value |
| TCGplayer order over $250 | Tracked, with signature confirmation | TCGplayer requires the signature |
| Booster case | Ground Advantage or a heavier-package service | Weigh it boxed; cases are heavy |
TCGplayer's own rules apply to every order: tracking is recommended over $20, required over $49.99, and signature confirmation is required over $250. Without them you "waive your ability to win any disputes" if the package doesn't arrive.
Set the right shipping rate
TCGplayer sorts products into four shipping sizes. Its own examples put booster packs in Small, booster boxes in Large and booster cases in Extra Large, and you set a rate for each size in Shipping Settings (full control from Level 4). If sealed is losing you money on postage, raise the Large and Extra Large rates rather than the Small one your singles use.
Labels for mixed batches
Most days are mixed: a stack of singles for envelopes and a couple of boxes. In TCG Speed Shipper, upload TCGplayer's Export Shipping file, set Print to Tracked only for the boxes and download their labels (or the Pirate Ship file), then switch to Envelopes only for the singles.
FAQ
What is the safest way to ship a booster box?
Box-in-a-box: keep the shrink wrap on, wrap the booster box in bubble wrap or kraft paper, and put it in a sturdy shipping box at least 2 inches bigger on every side, with the gap filled so nothing moves. Never ship a booster box with the label stuck on its own shrink wrap.
Which USPS service should I use for sealed product?
USPS Ground Advantage for most booster boxes and ETBs: it includes tracking and up to $100 of insurance. Add insurance above that for expensive product, and signature confirmation for TCGplayer orders over $250.
Can I re-shrink a booster box and sell it as sealed on TCGplayer?
No. TCGplayer's sealed rules say the item must be in its original, unopened packaging and "Not re-shrink-wrapped or re-sealed".
Does a dented box still count as sealed?
TCGplayer's standard for factory sealed includes that the packaging is undamaged and shows no damage or wear and tear, which is why the outer box and padding matter so much.
