Uni Pin Fine Line Brush Pen

The Uni Pin Fine Line Brush Pen gives artists, illustrators, and designers a tool that combines precision with expression. Filled with uni-ball’s fade-proof, water-resistant Super Ink, it delivers bold, pigment-rich lines that hold up beautifully, even when used alongside watercolours. That means you can layer washes over your drawings without fear of smudging.

What sets this pen apart is its flexible brush tip. It responds effortlessly to pressure, angle, and speed, letting you switch from delicate strokes to dramatic sweeps in one motion. Whether you’re exploring brush lettering, adding shading, or experimenting with expressive linework, the tip adapts to your style.

Built with a steel-supported nib for durability, the Uni Pin Brush Pen is a trusted favourite among professionals and hobbyists alike. It’s perfect for sketching, illustration, and design work — though it’s not made for permanent use on surfaces like wood, plastic, or glass. For paper-based creativity, it’s hard to beat.
