GlowCraft mugs use heat-sensitive technology. When you pour in a hot liquid (coffee, tea, etc.), the heat activates a special coating that reveals the hidden design. As the mug cools down, the design fades back to its original state.

No, our mugs are not microwave safe due to the heat-sensitive coating, which may get damaged in the microwave. We recommend handwashing only to preserve the design.

For best results and to maintain the longevity of the design, we recommend handwashing your GlowCraft mug with mild soap. Avoid using a dishwasher, as the high heat can damage the heat-sensitive coating over time.

All GlowCraft mugs have a capacity of 11oz, making them perfect for your favorite hot beverages.

GlowCraft offers a variety of designs, including popular themes like Star Wars lightsabers, Harry Potter's Marauder's Map, retro Game Boy consoles, and more. We're always adding new designs to our collection!
