Sealed product
Product still in its original factory packaging, unopened and untouched, sold exactly as it came from the manufacturer.
Sealed means the product is still in the manufacturer's packaging with the factory wrap intact: an unopened box, an unopened case, an unopened pack. Nothing has been searched, weighed or resealed. In collectibles, sealed is a condition claim as much as a description, and it is the claim the entire break economy rests on, because a break is only fair if the box really was untouched.
Sealed product sells in two completely different ways on a live show. It can be sold to stay sealed, where the buyer is holding the box as an investment, or it can be sold to be opened, either as a break or as a personal. Same box, same price, two entirely different buyers.
If you sell sealed product, show it properly. Turn the box, show the wrap, and let the camera confirm the seal before anything is opened. That single habit prevents the most damaging accusation a breaker can face.
