Studio 22 Artists Ruling Pen for Applying Masking Fluid

I got this to try using it for masking fluid on watercolour paper. It is fabulous. Easy to use, easy to change the width. Easy to clean and fairly inexpensive. I love it.

I've struggled putting masking fluid down on paper the past, it was always blotchy. Now the struggle is over. Lovely sharp lines, it's an excellent tool .

I used it for masking fluid with not very good results. Nothing wrong with the pen.

I bought this item to apply masking fluid to paintings. It works really well, can adjust the width of line. Good quality.

Good quality, good price , well made

This is a really handy little tool.

Don’t bother it doesn’t hold the liquid, easier to paint with a brush

I purchased this to use with masking fluid because of the point and firmness
