The product is made of the highest quality borosilicate glass, which is resistant to any tarnishing in the dishwasher and thermal shock. Thanks to the double walls, the vessel not only maintains the right temperature of the drink for longer, but also protects against burns. We can hold it in our hand without fear, even when drinking hot coffee. The glasses have a classic but modern shape that prevents it from slipping out of your hand. They are perfect for serving hot and cold drinks, and also look beautiful on the table.
