You ship a graded slab worth four figures. Two weeks later a return request lands marked "not as described," and the case that comes back is not the case you packed. You refund, because tracking shows delivery and the only record of what left your desk is the word "mint" in the listing text.
A return policy will not keep that request from being filed. No marketplace lets a seller opt out of it. What your wording can do is describe, in advance and in public, exactly what went in the box — including a number that was photographed before the package was closed. Below is that wording, the one-minute routine that makes it worth writing, and a plain account of where it runs out.
What a return policy actually sets
eBay’s own buyer claim process sits on top of whatever you write. A "no returns" seller still has to answer a claim that says the item arrived not as described, so do not draft your policy as if you can refuse returns outright. You mostly can't.
What your wording does control:
- The condition you describe. Same condition, original packaging, the numbered seal still on the case — all of that belongs in the listing and in your stated return terms.
- What sits inside the transaction record. A close-up of the seal with its number legible, used as one of the actual listing photos, is dated by the platform and visible to the buyer. A photo in a folder on your desktop is not.
- Refund deductions for items that come back altered, where your seller status and eBay's current rules allow for it.
- How specific your report is. "I think the buyer swapped it" and "the number on the returned case is ABC-0418; the case I photographed on July 9 was ABC-0392" are two very different sentences to hand a support rep.
Whatnot and TCGplayer run the same basic structure: the platform runs its own process and reaches its own conclusion, and what you can hand it is whatever you wrote down at the time. None of them treat a numbered seal as anything special. The number is not for them. It is what makes your own records specific enough to be worth reading.
The three pieces of wording
Copy these, swap the bracketed parts, and keep every sentence descriptive. Say what you do, not what you suspect, and never write a line about what the seal supposedly makes impossible — a buyer who reads that line and then peels one off anyway has just caught you overstating.
1. The listing blurb
Put this near your condition notes:
"This item ships with a numbered seal applied to the case. The number is [ABC-0000] and it is legible in the photos above. I photograph the seal and log the number against the order before the package goes out. If you return this item, please send it back with that seal still on the case. If a return arrives with a different number, or with no seal, I will note that in the return case along with the shipping photo and the log entry from that day."
2. The return-policy line
Shorter, for the policy field itself:
"Returns accepted within [X] days, in the same condition they were sent, including the numbered seal applied at packing. Every order ships with its seal number photographed and logged. Returns are opened on camera and the number on the returned item is matched against that log before a refund is issued."
Two words carry the whole line: photographed and matched. Neither one promises an outcome, and neither one can be argued with, because both describe something you actually did.
3. The return-received checklist
Tape this above your packing station and run it on every return, before you touch the refund button.
- Film the sealed package before opening it, with the shipping label and the condition of the box visible.
- Open it in one continuous take. No cuts, no pausing to reposition.
- Photograph the seal close up, with the number legible.
- Read the number aloud and match it against your shipping log and the listing photo.
- If it matches: inspect the card as normal and refund per your policy.
- If it does not match, or the seal is gone: pause there. Leave the packaging exactly as it arrived, upload the video, the close-ups and the original listing photo to the return case, and write down what you found in flat, unemotional language.
Marketplaces put deadlines on responding to a return, so run this the day the package lands, not the day the refund clock expires.
How this reads to honest buyers
A seal clause sounds hostile in your head. Written plainly, it isn't. Honest buyers already send things back untouched, so the clause asks nothing extra of them. It reads the way a serial number on a laptop reads: a sign that the seller runs an operation with records in it.
Two habits keep it that way. First, describe rather than accuse — "the number is photographed and logged" instead of "buyers who mess with the seal will be caught." Second, skip threats entirely. "Fraud will be prosecuted" reads angry and commits you to something you will not actually do. "A missing seal will be noted in the case with the shipping photo" is calm, specific and completely true.
The one-minute record that makes the wording worth writing
The templates above are only as good as the records behind them. Building those records costs about a minute per order.
- Apply the seal, then photograph it. Number legible, in focus, as one of the real listing photos — not a separate file you keep privately. Placement matters more than people expect; the format-by-format placement guide covers where it goes on each holder, and there are specific walkthroughs for a graded slab and for the outer shipping package.
- Log it. Order number, seal number, date, one line of description. A spreadsheet is fine. If you would rather not keep your own, My Seals holds a private record of each design and the date it was logged.
- Run the checklist on arrival. Then reconcile the three facts: the number you shipped, the number that came back, and the date on each photo.
What that gives you is not an argument about honesty. It is a short factual statement with dates attached, which is a much easier thing for a stranger at a support desk to read than a paragraph of frustration.
What a seal will not do
Be straight about the limits, because the moment you overstate one, everything else you wrote gets discounted along with it.
A seal is a sticker. It can be peeled off, and another one can be put on in its place. It does not decide a return case, and no wording you write decides one either — eBay, Whatnot and TCGplayer each run their own process and reach their own conclusion, and sometimes that conclusion goes against you. A seal record says nothing about the card inside the holder: it is a page showing the design, the number and the date it was logged, not a grading opinion and not a statement about what the card is. And a number on its own is just ink. It means something only because you photographed it on a specific date and wrote it down next to an order number.
What is left after all of that is still worth the minute. A numbered seal helps document what was shipped, and a number a buyer can read in the listing before they bid helps deter swaps and return fraud — not by making anything impossible, but by turning a vague suspicion into something you can describe precisely, with a date on it.
Set it up before the next order
Standard seals are 0.75 x 1.77 in, $6.00 per pack of 12, with a 60-seal minimum — $30.00, or 50c each. The rate steps down as the run grows: 45c at 120, 40c at 600, 36c at 1,200, 33c at 2,400 and 30c at 4,200, with self-serve ordering running up to 10,008 seals and larger runs quoted. The Large size, 2.5 x 1 in, is $9.00 per pack of 12 — 75c each at the 60-seal minimum, dropping to 45c each at 4,200. Two foils are available on both sizes, Shattered Prism and Aurora.
The numbering is yours. Pick a prefix and a scheme: sequential from a starting number you choose, random codes, batch codes, or no number at all if you only want the branding. You can add an optional QR that points wherever you want it — your shop, one listing, a live show, or your seal record. If you sell under a shop name, branded seals for eBay and Whatnot sellers covers what belongs on the face of one.
Build your seal, pick your prefix, and paste the three templates above into your next listing. Then photograph the first one before it ships — the wording is only worth as much as the photo sitting behind it.
