Review on 🗺️ Harry Potter Marauders Map - I Solemnly Swear - 16 oz Large Ceramic Morphing Mugs – Heat Sensitive Clue Mug - Full Image Revealed with HOT Liquid by Paul Monzon

I first bought similar mugs from Universal Orlando Gift Shop as Christmas gifts for my sister's kids as they are crazy about HP. Although they turned into a hot liquid as intended, the image shown was rather simple and boring. Gave them back. Found these and they were much better. The kids loved them! A small downside - the liquid inside must be very hot - hotter than children should drink to reveal the image. We boiled water, filled their cups so they could see the picture, then poured out the water and filled them with warm cocoa so they could drink it safely. Still a win!
