Schliersee Magic Heat Changing Coffee Mug Star Moon Ceramic Heat Sensitive Color Changing Cup， 15 oz

The mug is a standard 15oz size you find pretty much everywhere, and has a special painting coating on the outside that is heat-sensitive. It's fairly responsive and stays visible for quite a while as long as there's drink inside and it's hot. The material used for heat-sensitive designs is NOT machine-washable, it will scrape off during the wash cycle. The mug is ceramic though, and washes easily (and best) by hand with some soap.

The mug is a great size and the handle itself is great bc you can easily fit your hand through it. The stars and moon designs are great and come through super clear when you put warm water in the mug. Great value for the product.

It's a bit of fun when filling it with heated item to watch the design appear. Made well and I understand to no put this in the dishwasher to make it last longer. I like the size, the design and the weight of it.

I really liked this mug. The size and the design are perfect and the pattern reveal works nicely

Wonderful! I love it!
