Review on The Unemployed Philosophers Guild Disappearing Dino Mug - Color Changing Coffee Mug for Dinosaur Lovers - Heat Sensitive - Watch Dinosaurs Transform into Fossils! by Mike Starling

High-quality screen printing, almost embossed. It's fun to watch the skeleton's appearance. But I wish it could be machine washed. Not a huge downside, unless I'm worried that someone ELSE in the house will forget it and accidentally put it in the dishwasher, so I feel like I have to "guard" it. Bought as a gift for my son but took it with him. 😁 eh, the WORLD is not perfect; What are you going to do? Just grab a mug and enjoy the feel of high quality, but take good care of it. It is easy enough to clean with a soft cloth when hand washing.
