Viski Gem Crystal Whiskey Tumblers Set of 2 - 10ozA set of two Gem crystal tumblers from Viski, built around a faceted, gem cut base that catches the light. The solid base gives a firm, weighted grip, while the bowl holds a generous pour with room for a large cube or ice sphere. Each tumbler holds 10 oz and stands 3. 5 inches tall with a 3. 3 inch diameter. Hand washing is recommended to keep the crystal and its facets clear and bright. As good on the shelf as it is in the hand.
