I recently purchased the Heat Activated Funny Mug - 11oz Grade A Ceramic Coffee Mug/Cup - DOUBLE COAT MAGIC BLACK LAYER - Color Changing/Heat Sensitive - Humor / Funny Gag / Prank - Giftable Foam Box Included (https://www.amazon.com/dp/B07XCFY1VT?tag=absurdophile-20) and I'm very impressed with it so far! The mug is of top quality, a great gift idea for anyone who loves coffee and has an awesome sense of humor. It comes with a foam box protection to make sure no damage is done to the mug during shipping or storage.
When hot liquid is poured in, the image on the cup appears as if by magic, revealing an amusing design that will bring laughter every morning when you wake up. Just remember not to use this in either dishwashers or microwaves as it can cause damage; also making sure your drink is piping hot (70°C – 158°F) for best results!
Lastly, I love that my purchase came with a 100% satisfaction guarantee; no questions asked money back policy should anything go wrong upon delivery or from any other reason after purchase--highly recommend this product!
