Fineline Masking Fluid Pen Standard Tip 0.8mm - 18 Gauge 37.5ml

The Fineline Masking Fluid Pen with 18 gauge (0.8mm) standard tip is designed for artists who need reliable precision and control when preserving white space in watercolour work. Perfect for creating sharp highlights, intricate details, and clean edges, this applicator allows you to apply masking fluid exactly where you need it, without brushes or mess.

Ideal for illustration, botanical painting, and detailed watercolour compositions, the 0.8mm tip makes a great tool for both fine lines and slightly broader masked areas. It protects selected areas during washes, giving you greater freedom and confidence in layered painting techniques.

Engineered for smooth, consistent flow, this fineline applicator reduces clogging and improves accuracy compared to traditional masking tools, making it a reliable choice for studio and plein air use.

After use - take care when refitting the cap to ensure the needle goes into the bottle opening.
