Our insulated, double wall glass is handmade by expert artisans. Because this glass is mouth-blown, each one may have slight differences in height, thickness & weight. Please use care when placing ice into the glass to avoid fracturing the inner layer. We suggest placing the liquid first and then the ice. Please also avoid using metal spoons or placing the glass into a crowded dishwasher. These glasses will help to keep hot drinks warmer and cool drinks cooler. For best results retaining heat, pre-heat the glass before use. Dishwasher & microwave safe.

Note: You will find a small air-hole (blown hole) on the bottom of this double wall glass product, this is not a flaw but a safety means to control air pressure between walls. Normal circumtances, no dish washer, simply rinse with hot water. Clean the bottom gently, avoid brush, otherwise, there might be some water trapped inside the hole and fog up between the two walls. Mouth blown glass, each piece hard to make to perfection.
