Great for coffee mugs!
I finally found a paint pen for coffee mugs! These pens are easy to write and draw with, but the best thing is that the paint lasts! Follow the directions of baking the cup afterwards and then spray it with a sealant just to be safe. The mugs will hold the paint, wash after wash!
I like these better than the Sharpie paint markers
I paint on porcelain and I really liked these markers a lot. I heat set them for permanence and they don't dull in the process.
They also arrived in working order (other markers I had purchased elsewhere-- I went to use them brand new out of the pack and they were dried up or didn't work).
I'd recommend these over even the Sharpie paint markers!
Be careful when getting the paint to the tip for the first time.
They are about what I expected. I used one on a ceramic mug and tried two days later to rub the paint off with water with no success. That was without using a sealant. I have not tried to wash it in the dishwasher yet. One complaint I have is that some of the pens flow pretty heavy. When I opened the first one and pressed on the tip to get the paint to flow out it went everywhere. I recommend lightly tapping the tip several times on some scratch paper to get the paint flowing. The ones that I did not do that with now flow paint out very heavily and I can't use with stencils because the paint runs underneath. The tip is not that fine either. It is larger than a regular sharpie point. The tip is more rounded and not pointy. Otherwise the paint adheres well and the colors are nice.
