HAND-MADE, KILN-FIRED, BOROSILICATE GLASS: Borosilicate is the perfect glass for hot drinks. Compared to normal (soda-lime) glass, our borosilicate espresso mugs 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.
Keep your hands cool with our double walled glass coffee mugs, designed to keep your hot drink warm without burning your hands.
CHIC, UNIQUE DESIGN: Designed and manufactured by Espresso Parts, one of America's top cafe supply and accessory companies, Hearth double glass coffee cups feature a gorgeous angular design you won't find anywhere else.
DURABLE: Shatter-resistant, scratch-resistant, and microwave-safe, our set of 2 glass coffee cups will last a lifetime.
SATISFACTION GUARANTEED: We’re certain you'll love your Hearth espresso mugs! But in case something goes wrong and you're not 100% happy simply send us a message and we’ll make it right. Easy as that!
