This new storage cabinet adopts a multifunctional usage method, combining the storage cabinet with the bookshelf. The cabinet is divided into upper and lower parts, with a total of 4 layers. The closed part of the cabinet door has been designed with magnetic suction, which solves the problem of cabinet door closure caused by weather conditions such as air humidity, while ensuring the privacy of storage. In addition, after removing the cabinet door, it can be used as a bookshelf as a whole. The upper partition layer can be adjusted or removed, and display items of different sizes can be placed.
