Williams Sonoma Rabbit Freezable Whiskey Glasses

Sip whiskey, and other cocktails, perfectly chilled without ice, so your drink doesn’t get diluted. The double wall design holds a food safe, freezable liquid; just place the glasses in the freezer for at least an hour before pouring drinks. These glasses instantly chill beverages for up to two hours. They are made of double walled BOROSICLICATE glass. Black silicone base acts as a built-in coaster to protect tabletops and shield your hand from the chill. This set includes two 8 ounce glasses. Never have been used.
