The Duo Glass is a hand blown 10 oz double wall borosilicate glass that is crafted to insulate, measure, and compliment your every drinking experience. 

The double wall design of the Duo glass insulates better and reduces condensation so that no coasters are necessary.  The rounded inner glass perfectly cradles a large ice ball - a silicone ice mold is included with every glass. The integrated 1 oz measuring lines blown into the inner glass wall allow for easy measuring and make it a cinch to craft cocktails directly in the glass.
