Specially designed for roller skaters to store bearings, this storage case can effectively store and carry bearing sets of roller skates by virtue of its restraint structure and stable fixation. It offers roller skaters more convenience, and provides more possibilities for roller skating. The product distinguishes itself with its multiple shapes stimulating the motions of skating racers, leading to a sense of liveliness.

The storage box is composed of two combined and eccentric cylindrical storage chambers, a bearing tool and a silicone belt. The purpose of the eccentric treatment is to make room for invisible hinges, making the appearance more rounded and beautiful. There are bearing limit ribs inside the storage cavity to avoid noise caused by carrying. The bearing tool can be inserted into the middle of the box body, and the tool is responsible for holding the storage box tightly, and it is more convenient to carry through the silicone belt. The design fully takes into account that the appearance is body-shaping, but the specific gravity after loading is a metal box. It must take into account the appearance and the gravity point. The eccentricity also takes care of the reliability and stability of the hinge structure.
