Want to pull a prank on your boss or co-worker? This is the mug for you. Give it to them as a gift and watch the hilarity ensue when they realize what is hidden beneath. As soon as hot liquid fills the cup the image beneath begins to be revealed.

Birthday, Christmas, or anything in between!

I make these mugs at home myself, using sublimation, and I am very proud of them. I am happy to do custom designs as well, if you have a request! Any questions, feel free to ask! Ships FAST!
