Solar System 12 oz Heat Changing Magic Coffee Mug Heat Sensitive Porcelain Tea Cup Funny Gifts

Do not buy these unless you love hand washing your mugs. If you put them in your dishwasher the film on them that makes the appearance change peels off and you'll be left with a plain black mug that you overpaid for.

Very fun and nice. It has mistakenly ended up in the dishwasher and has held up nicely, but beginning to get a couple of spots in the print. Keep away from dishwasher as much as possible.

My son picked this out for a birthday gift for my brother because my brother loves anything to do with the solar system. He absolutely loved it and sent us a video of it changing.

This is my favorite mug. I love heat changing mugs and this one worked beautiful. I don't recommend putting them in the dishwasher but wash by hand and they'll last a long time.

Barely any change. Even filed with boiling water, planets are hardly visible. Too expensive for a cup with a bunch of dits on it.

This is the perfect gift for someone who loves science. My uncle is a science buff. He loves the mug, So much that he uses it everyday.

Great item, but it is not dishwasher safe!

Cute mug changes color

A beautiful mug even without hot coffee.
