1, the mobile phone case is made of materials jointly developed by Wuhan University, which is hollowed out in a large area and can absorb moisture in the air. When the mobile phone is hot, the water will evaporate, and when it evaporates, it will absorb the heat generated by the mobile phone, which can reduce the temperature.

2, Kevlar material, the material features light and thin, good heat dissipation, good feel, and will not change color and deformation.
