PEBEOMarker Drawing Gum Nib - 4mm, Round

Not sure if this is a fault with the product or the nature of masking fluid, but the nib gets blocked quite easily. you need to be careful and clean regularly. I also found the nib quite thick so struggled with fine detail - I resorted to "painting" my pallette tray and dipping a brush into it when doing fine lines

Excellent product. Easy to use.

Dry and hard to use

I bought this gum pen to use when I am painting watercolours. It works well on most papers & cotton papers but not that good on wood pulp papers which luckily I do not use that often. You use it just like a standard pen, draw your picture etc, let the gum dry and as long as you do not leave the gum on your paper for longer than 7 days, the gum rubs away (either by fingers or a rubber) with no problems. The 4mm is quite wide. Very pleased with this product.
