They are made of hand blown, heat and shatter resistant borosilicate glass which is stronger than normal glass. Not only does the double wall design look awesome, but is also keeps your drinks at the right temperature without your hand getting hot or cold while holding it. They are also microwave, dishwasher, and freezer safe! These little glasses are just all around awesome!
I love my Ozeri Serafino glasses. They are not only adorable, but durable which is important in a house with two children. They keep my cold drinks cool and my hand away from any condensation. On the other side, they keep my hot drinks hot while keeping my hand cool. They really are a unique glass and I will definitely be ordering more to have a full set! Be sure to head over to Amazon and order a set for yourself and see all of the other products Ozeri offers!
