Pilot New Brush Pen - Medium
The brush tip is made of special fibers that mimic the feel of writing with an actual brush. The synthetic brush tip is especially durable, about three times more than the hair used in typical brush pens. This allows it to retain its shape well.
The brush pen uses smooth-flowing, richly pigmented, dark black ink that is water-based and dye-based. The ink cartridge is easily refillable.
