Keep cool drinks cool hot drinks hot. Cheers to this glassware for pulling double duty! Its unique mouth-blown double-wall design provides extra insulation so your Chardonnay or Chablis stays at its proper serving temperature regardless of how long you"ve held the glass. It also creates a "suspended" visual effect for a compelling presentation. Use for hot tea and coffee too! Stable durable design made of lead-free glass. Dishwasher safe. Size: 4"H x 2-3/8" Dia. 7 oz.
