The Tritan material of the cup body is provided by Eastman Company of the United States. This material does not contain BPA and meets the requirements of food-grade materials. Good flexibility. A cup filled with water will not break even if it falls to the ground when it is less than 1.7 meters.

Transparent and hard, it never contains BPA, a harmful substance of bisphenol A.

Easy to drink. As long as the "automatic sealing" button is pressed, the water in the cup will flow out from the small hole in the lid without opening the lid. When the button is released, the cover will automatically lock, 100% leak-proof and 100% spill-proof.
