they are amazing ! what's the name of the pen? I wanna have cups like this :( do you sell this? you make me wanna try painting on cups even that I'm not that professional at painting :) some day I will try and if I did well I will show u :)
The pen is just a sharpie, and I used a small children's tea set from the craft store, which came with it's own paint! I've stopped selling them though. I definitely recommend trying your hand at painting on cups!
