In online marketplaces, NIP stands for “new in package.” Sellers use this acronym to refer to items that are brand new and still in their original packaging. You can find this practice on websites such as eBay, Facebook Marketplace, or specialized reseller communities for various product categories. It’s frequently combined with “condition,” which is the part of a sales post where the seller states the item’s current status. A similar term, “NIB,” means “new in box.”
