Love these markers! They are clean and colorful.

I use this on my watercolor paper.

Love that you can turn the tips around to make it a fine point or medium point!

I love these chalk markers and buy them over and over. They are bright and easy to use.

I love this product

Works great

Great service

Not very vibrant on glass. You really have to work it to get the ink to the tip. I was expecting bright and bold like Sharpie brand colors usually are.

I tried those markers on my plastic binder cover which is black. The colors are vibrant. However they are very watery compared to paint markers of other brand. I could not get a smooth opaque texture at all.
