This set of 4 Avva Small Tumblers includes two of each of the Avva shapes - ST1 and ST2. Specifically designed for Whiskey, the glasses work equally well for any one of your favorite spirits where quality is more important than quantity. Each glass is handmade and hand-polished using a compund that is usually reserved for optical lenses. Despite their unique appearance, the glasses are made to be used and are dishwasher safe.
