Review on Pebeo Drawing Gum Marker: 🖌️ .7mm-Natural Latex Pen for Precision Artwork by Carrie Spencer

This product works great! It doesn't need to be stirred as often as other concealers I've used (stir rather than shake to avoid blisters). Also, I can blow dry the painting a bit without worrying about it sticking to the paper. First I put a little dish soap on my brush to protect it and the masking liquid is easy to remove when I'm done. I used this to ensure the masking liquid was completely dry before applying watercolor to it and to ensure the paint was completely dry before removing the mask. When I scan my watercolors after completion, I notice microscopic liquid crumbs left on the paper. But they're easy to remove once I know where they are. I haven't left the mask on for over a week so I can't comment on how easy it is to remove after a long time but in my experience this is a fantastic product!
