Martial artists are urged to cultivate a beginner's mind set or to "empty their cups." We added a little surprise to the process with this color-changing coffee mug. When empty, this mug has a black matte finish. As you fill it with the delicious hot drink of your choice, the mug reveals its secret.
- Black matte finish when cold
- Reveals the print when filled with hot liquid
- Dimensions: height - 3.85" (9.8 cm), diameter - 3.35" (8.5 cm)
- Made in China. Printed in Europe
- Handwash only
Note that an outline of the logo may be slightly visible when the mug is empty. We recommend filling this coffee cup with our own coffee (available at https://theimmortalcoffee.com).
