The Texas Longhorns 12 Ounce Tumbler Set is a set of 4, gift boxed tumblers, and is constructed of high-grade clear polycarbonate with double wall insulation which keeps your drinks hotter or colder than glass. The Texas Longhorns 12 Ounce Tumbler Set is dishwasher (top rack), microwave, and freezer safe and is virtually unbreakable. College logos are embroidered and placed between the double wall construction. Makes a great addition to any fan’s collection.
