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

Cute and innovative. Everyone was amazed when it was rolled out and explained. The design is unique and perfect for any HP fan. I wish it was a little smaller to heat more of the design (cup size is larger than regular brew size). I wish it was dishwasher and microwave safe, but I understand it probably won't ruin the temperature-changing design forever.

No evidence of a "latent" image at room temperature, which many similar mugs do not have. 16 oz is the perfect size for those of us who need a big coffee to start the day. The artwork is beautiful and detailed when unfolded and will last until it has cooled most of the way. My only complaint (which doesn't apply to this mug) is that the transforming mugs are not microwaveable. Not that big of a deal, but for some it can be a deal breaker.

I bought this mug as a Christmas present and my boyfriend loved it! (she's a huge and perceptive Harry Potter fan) She uses it all the time. I've looked at a lot of these morphing mugs but this one was my favorite because it had the design and the words on it before it got hot while many of the others were just black before the picture popped up. The image appears quickly and has a lot of detail. It's very sweet no matter you drink something cold or hot!

This Gryffindor mug is magical! At least that's how it seems! As long as it's cold, it looks like an ordinary black mug with "You belong" written on it. on the bottom and the gold outline of the Sorting Hat on the opposite side, and then as soon as you add hot liquid for coffee or tea, the Gryffindor symbol magically appears! The change is instantaneous and the colors will stay on the mug while it's warm! The mug itself is solid. A must for Gryffindor fans!

I love this mug! I've seen variable temperature mugs before, but didn't really like the design. The only downside is that the part of the mug that stays black looks a little sloppy because it's not straight, but I'm sure that's the case with all these types of mugs. so that the whole image appears (my coffee pot only makes 12 ounces) that wasn't as hot as the coffee or tea so the top image didn't disappear entirely.

Item arrived on time and in good condition. The packaging was a very strong box with just enough padding to keep the mug from shifting during shipping. The contents were not specified on the packaging. So if you are giving a gift, half a sheet of wrapping paper is fine to cover it. Or, if you don't have any wrapping paper at home and aren't leaving the house because of the pandemic, just put a bow on it and you're done. Oh and I love the mug, I'm a huge fan of the Harry Potter books and I'm…

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

The writing is somewhat visible when the mug is warm. Since I ordered this in winter, it is mostly visible in cold ambient temperatures. But I see that it works by pouring hot water (sort of in reverse). I also ordered a black mug that reveals when hot liquid is added. The black cup is a lot harder to see when it's supposed to be invisible, and I'd recommend it unless you really want to use it for icy liquids. Gave this and the black mugs to the Harry Potter fanatics in my family and they loved
