A little bit of a trip for your morning brew, these 14 oz mugs are made from white stoneware and glazed to create a drippy, trippy effect. These mugs are microwave-friendly and dishwasher-safe, though hand-washing is recommended to prolong their life and durability. Each JustinReis Ceramics piece is handmade and unique with marks and movements that show the artist's hand. Down with machine-made perfection. Up with local potters.
