Keep your coffee insulated for a longer period of time, yet cool on the outside for safe handling. Good news - this product is dishwasher safe. So there is nothing to get in the way of convenient cleaning. Double-walled design to maintain temperature perfectly - The coffee should be hot, not your fingers. That's why these glasses are double-walled. You can hold the glass from the outside without any problems and at the same time your coffee stays nice and hot. Made of high-quality borosilicate glass. A strong material for a heavy use - borosilicate glass. This material is ideal for glasses that are used every day because it is very temperature resistant and insensitive to heat.
