These charming tumblers are designed for coffee on the go. They conveniently fit in car cupholders, and just as comfortably in your hand if you walk to work. Wheel-thrown earthenware. Handpainted in warm chocolate brown over a cheery background color; coated with a clear, glossy glaze that also lines the natural red clay interior; brown silicone lid. Dishwasher safe, though hand washing recommended.
