Mug does exactly what the description says it does. Provided hours of fun for everyone in the office and there were some heated arguments over who got to have first use of it. HOWEVER, the novelty (literally) wore off as soon as it was washed. The description says it is dishwasher safe but we erred on the side of caution and hand washed it. The outer layers of the mug that reveal the “unt” to c. As a result the mug is no longer novel, it’s just kinda sad. Not too upset as it was on sale at six dollars, but be aware that it’s pretty delicate and should be washed with caution (maybe stick to rinsing with hot water). Still – great fun while it lasted!
