NIB

What does NIB stand for in online marketplaces?

New in box

On online auction and sales sites, NIB stands for "new in box." A NIB item is in mint condition and has not been removed from its original packaging.

You're most likely to encounter NIB while shopping for electronics or collectibles. Those items' condition can greatly affect their price, so sellers go to great lengths to point out when an item is not only new, but has never been opened. You may also see sellers use acronyms like MIB, BNIB, NIP, and NWT to describe unused, mint condition items.
