"Mint In Sealed Box". Designation for a collectible item that comes in perfect condition inside a factory sealed original box. This doesn't say anything about the condition of the box however, except that it can't be too smashed up as the item inside probably wouldn't be in mint condition then.

As any item inside a factory sealed box usually will be in perfect condition, and it's hard to mistake a box with shrink wrap from one without, this term doesn't have the potential to be as abused as, for example, MIMB. As a buyer you'll therefore be almost certain to get your collectible in the mint condition you're looking for, even though the box may be slightly damaged.
