My Favorite Things Personalized Color Changing Coffee Mug

I purchased one of the "My favorite things" color-changing photo coffee cups in the past for my dad with pictures of him and my daughter on it, and he loved it. We just purchased one for my mother-in-law for her upcoming birthday. The pictures came out clearly. When nothing is in the cup, it appears black, but when a hot beverage is added, the pictures all show up. I put different pictures of the grandkids. She is going to LOVE it! The coffee cup is lightweight, not heavy to hold. I highly recommend this cup!
