Blue Watercolor Masking Fluid Pen

WELCOME TO CREATIVE CRAFT SPHERE!

This watercolor masking fluid pen is designed to protect highlights and fine details while painting. Filled with blue-tinted masking liquid, it allows you to clearly see covered areas and easily remove them after painting, leaving clean white or untouched spaces.

The 0.7mm fine tip is perfect for delicate lines, small highlights, and detailed work, while the 3.0mm tip is ideal for covering larger areas quickly. The smooth-flow marker design offers better control than brushes, making masking fast, precise, and mess-free.
