The black cat in the window mug is magical. I didn’t know what a morphing mug was when I got it. When hot the cat appears and cold it looks like a plain black mug. .

I wanted to create a Christmas gift for family and friends. I used a photo I had taken of my peacock. When the mugs arrived I was anxious to try it out. It’s amazing to watch as the peacock “magically” appears! The mug itself is great quality and the morphing is beautiful to watch! The colors are amazing!
