Product Review

You did it! Congratulations! World's Best Cup of coffee!

We don't know how good your coffee is, but pouring it into this mug makes Buddy the Elf appear and that definitely gives it some bonus points.

The exterior of this officially licensed 11oz mug transforms from black as hot liquid is added, revealing the hidden image in full vivid colors.

While this mug may be used in the dishwasher or microwave, for the longest lasting, highest quality product, we strongly recommend against it.
