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.

• Instantly chills beverages for up to two hours.
• Made of double-walled borosilicate glass.
• Black silicone base acts as a built-in coaster to protect tabletops and shield your hand from the chill.
• Set of two 8-oz. glasses.
