Borosilicate Material, BPA free, Lead free, Baby safe. This is the best choice when you need a coffee mug to enjoy coffee, juice, tea, beer and more. Even if you pour hot tea into the cold mug, it won’t break. This material can bear 0 to 300℉ temperature difference.
Beautiful design with the benefit of the double glass wall to keep the cup cool to the touch. The handle is made of heatproof glass material. So you don't have to worry about if your hands will be burned when you drink hot tea. This is incomparable to a single-layer glass or ceramic cup.
We have more than 18 years of glass production experience and 5,000 kinds of product inventory. We hope to listen to your voice and start the first step of cooperation together.
