★ LIGHTWEIGHT BUT NOT FLIMSY ★ - Double insulated glass coffee cups feel lightweight, Compared to normal (soda-lime) glass, our borosilicate espresso glass cups are much harder and stronger, they are more heat-resistant (enough to safely pour in boiling water!); and they stand up better to acidic drinks. Borosilicate is environmentally friendly, BPA-free and widely used in high-end cookware and drinkware.
★ INSULATED DOUBLE WALL DESIGN ★ - Ideal for hot or cold drinks. Keeps your beverage the perfect temperature without burning your fingers when enjoying hot drinks with insulated glass coffee mug, and without sweating or creating condensation when using it for cold ones.
★ WIDELY USED ★ - Each of the glass coffee cups set holds 8 ounces to the rim, which is small enough to go with espresso machine as well as coffee maker
