UPG The Unemployed Philosophers Guild Heat Changing Constellation Mug - Add Coffee or Tea and 11 Constellations Appear - Comes in a Fun Gift Box, 12oz

I was concerned when reading some reviews that the outer film (with the thermal design on it) would come off easily, however if you follow the washing instructions written on the box carefully, you'll be fine! This mug has been an absolute star! (if you pardon the pun)

Got this as a birthday present for my daughter and she loved it when the different star designs showed after adding a hot drink

This is a great mug and comes with a film over the surface which is removed befor use. It does look like the heat sensitive layer is not very well bonded to the mug compared with other mugs we have had but so far with careful hand washing it's been totally fine.

Excellent product and Seller

Anthony Wesley 2/9/2018 Amazon Product Review: Color-Changing Mug Recently, I purchased this color-changing constellation mug from Amazon. I absolutely love it!. I decided to buy this mug for my beautiful girlfriend, who loves to look at stars every time we walk outside. It was part of a Christmas gift for her. I am so happy I bought it. I would definitely rate this product 5 out of 5 stars. Overall: To evaluate this product, I used simple criteria. One: the insulation of the mug. With this specific mug, I realized that it was a great insulator of heat, keeping my girlfriend’s coffee warmer for a longer amount of time than her average $3 mugs from Walmart. Appearance: Another criteria of judging I used was the overall appearance of the mug. This specific mug aside from it’s amazing color changing qualities, has a very smooth and shiny seal all over it. Making the mug easy to clean and easy to hold. When you first see the mug, it looks plain black and has stars all over it, even the handle. When you put hot liquid in the mug, (ie: coffee, hot chocolate, tea..) the entire mug changes color to let the owner see constellations clearly outlined all around the mug! The effect of the color-change is extremely fascinating overall. Functionality: It totally brings the mug to life in a fun way. Using this mug makes waking up early for class or work an even better experience as it wakes you up and reminds you of something amazing, the stars and constellations. As the liquid cools down again, the mug changes back to a plain black color, making it also reusable. The negatives about this product are that the handle of the star mug does not change color, but scientifically it makes sense why it wouldn't. The mug also is preferred to be hand washed only. I understand why it is not machine washable because it is so sensitive to heat, but it does make it a little more cumbersome to clean. Utilization: Lastly, I think this mug is perfect for those who live in cold weather (and enjoy hot drinks), or college students (who are fueled on coffee). This mug would even be perfect for learning children as when the constellations appear they also have names to go along with them so they understand. There are also nontraditional ways yo use this mug. I have commonly used this mug for the consumption of ice cream and it works perfectly when I also want to cool off on a hot day. My girlfriend drinks coffee at least 5 times per week, and she uses this mug as often as she can! I strongly recommend purchasing this mug!
