Bottom: Silica Gel Bottom Concave and convex design to increase friction.
Leakage-proof sealing plug for cup cover: The use of high temperature sealing rubber plug can lock the water intake very well, making the tea not easy to spill out.
Cup Liner: 304 stainless steel inner wall smooth microwave copper plating, increase the time of insulation, effectively prevent bacterial growth
1. 304 stainless steel：
Our products, whether in cup or liner, are made of food grade 304 stainless steel, BPA-free, highly resistant to rust and corrosion, drinking water is healthier.
2 Vacuum insulation：High vacuum layer, no space between the stainless steel walls, reducing air heat transfer, the temperature of the liquid is not affected by the temperature outside the container. The inner wall of the stainless steel uses mirror technology to reduce heat radiation.
3. No condensation on the cup wall：When a hot liquid is added to the cup, the temperature of the liquid does not affect the outside of the cup, there is no condensation, and the wall of the cup remains dry.
