  • Beverages seem to float within our sleek double-walled coffee cups, a fun effect that serves a very practical purpose. The two seamless walls of borosilicate glass create an insulating layer of air, so coffee and tea stay piping hot and delicious – yet the cup always feels cool to the touch. The durable glass is great for everyday use and casual entertaining.
