／ Welcome to #RuuKitchenShop ♡ ＼ ✨【Glass Material】The tumbler glass uses borosilicate glass, which is heat-resistant and can withstand temperature differences from -20℃ to 150℃, so you can use it with ice or hot water. ✨【Double-Walled Glass Cup】The glass has a double-walled structure, which not only provides heat retention but also cold retention, making it difficult for ice to melt. It's a glass with excellent heat and cold retention that keeps your drinks delicious. You don't have to worry about burns even if you put hot water in it. ✨【Prevents Condensation】The double-walled glass structure keeps the temperature gentle to the touch, whether it's cold or hot. It doesn't cause condensation on the surface when hot water is used, and it's also less likely to cause condensation on the surface of cold drinks with ice, so you don't have to worry about important documents getting wet on your desk in the office or during telework. ✨【Please Note】※Because each item is handmade by craftsmen, there may be slight individual differences. The silicone vent on the bottom only allows air to pass through and prevents water from entering. Please use it as is without peeling it off. ✨【Specifications】Capacity: 340ml.
