This set of 2 double walled espresso glasses from Danesco have a capacity of 200ml / 6.8oz and are made from lightweight, thermal, shock resistant borosilicate glass. The double wall captures air to create a vacuum layer of thermal insulation and thus, keeps your coffee or cappuccino hot longer while the outside layer remains cool and safe to touch. These cappuccino cups can also be used for cold drinks as they prevent condensation. The cappuccino glasses are dishwasher safe and come in a nice gift box.
