Bodum's insulated, double-wall glass is handmade by expert artisans. This glass is mouth-blown, so each one may have slight differences in height, thickness, and weight. Each glass is individual! These glasses will help to keep hot drinks warmer and cool drinks cooler--for best results, pre-heat your glass before use. Dishwasher and microwave safe!
Use care when placing ice into the glass to avoid fracturing the inner layer--place the liquid first and then the ice. Please also avoid using metal spoons or crowding the dishwasher.
