The Pentel Brush Pen XFP5M has a medium tip and uses water-based pigment ink. The ink dries quickly, produces vivid color, and is designed to minimize ink bleeding, allowing clear, dark writing on absorbent paper such as washi.
Features
The pigment ink has water and light resistance.
When used for drawing, watercolor paints or poster colors can be applied over the dried ink while retaining vivid color.
The brush tip is made of nylon fibers, with individually tapered strands extending through the tip.
