Color Changing Grandpa Mug
Our black coffee mugs are made of high quality 11oz ceramic with good durability. The mugs have glossy exterior and interior. They come with C curved handle which gives a easy and comfortable grip. The print can cover almost entire exterior of the mug except the area behind the handle and a tiny line on top and bottom of the mug. These mugs are heat sensitive and as soon as the hot water or coffee is poured the color changes from black to white and the image on the mug appears.
This is a great way to surprise grandpa with a great news of pregnancy and having a child. The message says ” You are going to be a Grandpa” and on the other side arrow pointing up says “This guy is going to be a Grandpa”.
