The Double Walled Wine Glasses by True come as a set of two clear, 10-ounce stemless glasses made from borosilicate glass. Their double-wall construction provides insulation to help maintain beverage temperature and limit condensation on the outer surface. The stemless shape offers a stable base for serving red wine, white wine, cocktails, and other drinks. Each glass measures approximately 2.75 inches wide and 4.5 inches tall. The glasses are dishwasher safe for convenient cleaning after everyday use or entertaining.
