What are the benefits of double glass?

1. Beautiful and practical. Most of the double-layer glass is made of high-quality high-borosilicate crystal glass. The surface is smooth and comfortable, the transparency is very high, the abrasion resistance is good, it is resistant to acid erosion, does not leave odor, and it is very easy to clean Beautiful and elegant, lead-free, non-toxic, safe, healthy and easy to use.

 2. Thermal insulation design. The glass body of the double-layer glass has two layers of glass with a certain space in the middle. This design keeps the temperature of the liquid in the cup not too fast. Drain, guarantee that it will not be hot, and designed to be convenient for people to drink. 

3. Resistance to temperature changes. Ordinary glass can't withstand sudden and sudden temperature changes when it suddenly encounters boiling water, but it will burst. But the double-layer glass is different. It is fired through a high-temperature process, and can withstand instantaneous temperature differences of -20 ° to 150 °. It has a strong ability to adapt to temperature changes and is not prone to chipping. 

4. Leak-proof design. There is a seal ring inside the lid of the double-layer glass. The design effectively prevents liquid leakage and can be carried with confidence. This layer of sealing ring is compounded with national medical grade safety standards and is safe and reliable.
