The Burnt Chef Project - Reusable Coffee Cup 12oz
 
Save Money - All coffee outlets will fill your own cup for you instead of their disposable versions and some will even knock a bit off the price of your latte if you bring your own flask. And I believe you will be very proud of your contribution to environmental protection.
 
Safe Materials - Made of durable and Food Grade Silicone. Silicone cover and ring are Free From BPA and Phthalates. Endures a wide range of temperatures from -50℃ to 200℃. It can be used in microwave and fridge. (Note: If you want to use a microwave to heat the cup, please remove the silicone first, otherwise the high temperature will cause the silicone to deform)
 
Durable - Highest Quality Borosilicate Glass for extra durability. Our glass won't taint the taste of your drink like plastic/bamboo. Feature elegant design reusable coffee cup is suitable for all people. 
 
Heat-Proof - The silicone ring makes the mug much easier to hold, drink from and heat protection. Although when the hot liquid in the cup is above 80℃, the silicone ring will be cool.
