Our mugs are made using fine white ceramic with a beautiful glossy glaze finish. Each design is pressed onto the mug using 400' heat so that the art becomes part of the mug. Not vinyl decals or stickers. Microwave & top rack dishwasher safe. We have been in business since 2018 and really love what we do! Colors may vary slightly depending on monitor/tablet/phone settings. Our mugs are handpacked in heavy duty boxes to ensure safe arrival
