Our new SPEBSQSA 1950's style diner mug was hand crafted just for you. Created by Deneen Pottery in St. Paul, Minnesota, each superior quality handthrown pottery mug features the crisp detailed SPEBSQSA emblem. Each piece is touched by over 24 pairs of hands and although amazingly uniform, no two are exactly the same. Kiln fired to 2150ºF, each piece is durable and safe for the microwave, dishwasher, oven and freezer. All stoneware is lead free & food safe. Mug is navy with a powder blue and white glaze.
