The Ruling Pen is perfect for applying Masking Fluid to your paper.

Dip the ruling pen in the masking fluid and 'scratch' onto your paper, creating very fine lines that will be masked against the paint. Once you have painted your picture, you can remove the masking fluid to reveal very fine lines of unpainted areas on your paper.

Great for grasses, small branches, rope, and other fine detail.

Length approx 13.5cm long.
