We love using our Joy Jolt Aroma Double Wall Coffee Glasses. They add a touch of class to my morning coffee. They work great for my favorite beverages hot or cold. The double wall glass keeps the beverage hot while keeping the mug safe to touch. The mugs are dishwasher, microwave and freezer safe. Drinks look so professional in the clear glass design.  Best of all the mugs hold 13.5 oz of our favorite drink!
