Mouth-blown borosilicate glass mug that is lighter and more durable than ordinary glass, with a comfortable grip. Insulated double-wall design keeps the exterior cool to touch, prevents condensation, and protects your hands from burns. It also helps keep hot drinks hotter and cold drinks colder for longer than single-wall glass or ceramics. 8-ounce capacity, suitable for use with most espresso machines and coffee makers. Microwave and freezer safe for reheating and chilling beverages. Dishwasher safe, but for best longevity and clarity, hand washing is recommended. Safe packaging prevents breakage during shipping and the clear mug comes wrapped in a gift box, making it an ideal gift for family and friends on special occasions. Use scenarios: - Start the day with a quick 8-ounce espresso or strong coffee drink, enjoyed without warming your hands. - Refresh with iced coffee, cold brew, or tea, while the exterior stays cool and sweat-free. - Serve guests hot chocolate or specialty teas in a stylish, gift-ready mug.
