When you bring home The Road to Better Days Podcast's Magic Mug, it changes color to reveal a secret design when filled with your favorite hot beverage.
• Ceramic
• Black matte finish when cold
• Reveals the print when exposed to hot liquids
• NOT dishwasher or microwave safe
Note that in some instances the coating might not be 100% opaque and an outline of the design might peek through a little. Also, you shouldn't put the mugs in a microwave or dishwasher since it can damage the coating.
