Viski Crystal Mixing Glass for Stirred CocktailsViski's crystal mixing glass is built for stirred cocktails. The heavy crystal carries a satisfying weight, the weighted base stays steady through a long stir, and the wide mouth takes large ice cubes with room to spare. At 17 oz, there's plenty of space to build a rye Manhattan or Old Fashioned over ice. It stands 7 inches tall and arrives with care instructions. Dishwasher safe, though we'd hand wash to keep the crystal clear over time.
