I am selling this item because I have kept it at home but have not used it. This is a double-wall tumbler made of heat-resistant glass with a capacity of 220ml and can withstand up to 120°C. - Brand: POKETLE - Model Name: vidro220 - Capacity: 220ml - Material: Heat-resistant glass - Maximum Temperature: 120°C - Dimensions: Diameter 80mm x Height 130mm This tumbler is entirely made of glass, including the lid. The aroma, temperature, and taste. And the appearance. A moment of relaxation during work, your usual coffee or tea will taste the best. You can use it with hot or cold drinks, and it's safe because of the double-walled glass. With its cute appearance, this Poketle glass tumbler will lift your spirits. It keeps hot drinks warm for a long time and prevents condensation with cold drinks, so it's safe to use on your desk. The smooth drinking spout on the glass lid does not impair the aroma or taste of the drink and does not transfer odors. A non-slip silicone band is included, which fits comfortably in your hand and is safe. Made with high-grade heat-resistant hard glass. Heat-resistant, cold-resistant, and BPA-free. Dishwasher safe. I am also selling different sizes.
