Inventory is a place that contains all users' current NFT items and users can refer to all stock here at any stage. Users' inventory in beFITTER has three separated spaces, including: shoes, boxes and pets. An NFT shoe has 2 stages, from a box to a shoe. In the box stage, the NFT will not function fully as a shoe, so users cannot use this NFT to move to earn. Unboxing is required to have an NFT shoe for valuable moving.
