This pack of 12 Pilot Fine BPS-GP Ballpoint Pens is perfect for smooth, reliable writing at work, school or home. It is packed with oil-based black ink that flows smoothly and dries to a water-resistant finish which helps prevent smearing when wet. A fine 0.7mm tip provides a crisp line that is ideal for fine detail when writing. The sturdy hexagonal barrel is transparent, so you can easily view the remaining ink level, and it is topped with a strong metal cone.
