Pilot Oil-Based Ballpoint Refill, BRFS10, 0.5mm

The BRFS-10EF features "Acro Ink." Acro Ink is a newly developed oil-based ink from Pilot that provides smooth, dark writing with excellent initial flow. Compared to our other oil-based inks, Acro Ink has approximately 1/5 the viscosity, and by incorporating a lubricant, it reduces friction at the pen tip, resulting in smoother rotation and a smooth, dark writing style. Of course, it also boasts the excellent water resistance characteristic of oil-based inks. *Compatible with BRF-8* *The tip has a color indicator showing the ink color.* [Color] Black [Tip Size] 0.5mm (Extra Fine) |
