Perfect for fine details!

The 0.7mm tip is a game changer for my botanical illustrations. It allows me to mask tiny veins in leaves without messing up the surrounding area. Dries quickly and peels off cleanly.

Great tool, needs careful cleaning

Works exactly as described. The fluid flows smoothly. Just make sure to clean the tip immediately after use, or it can get clogged. Overall very satisfied with the precision.

Good value for money

Lasts a long time since you only use a little bit at a time. The pale blue color helps me see where I've applied it, but it doesn't stain the final painting. Would buy again.

Essential for gouache artists

Works beautifully with gouache as well as watercolor. The mask holds up against multiple layers of paint. Removal is satisfying and leaves crisp white edges.

No more messy brushes

I used to dip brushes into jars of masking fluid and ruin them. This pen format is so much cleaner and easier to control. Highly recommend for anyone doing detailed watercolor work.

Excellent for splatter effects

Used this to create starry night scenes. The fine tip lets you flick small dots easily. Removes without tearing the paper if you let it dry completely first.
