This aesthetically pleasing Double Wall Silicone Base Glass Mug features a double wall and glass handle, giving the impression that the liquid is being suspended in air. The double wall acts as an insulator, keeping cool liquids cold and hot liquids warm without heating up the glass, without over-heating the glass. The cool grey silicone base further protects surfaces from heat damage.
So much more than a glass mug... perfect for herbal or black tea. The double glass layer is very attractive whilst the silicone base is very practical... less likely to break! We love them!. Julia. Denham Uxbridge, GB. Sun Apr 07 2019
