Ergonomic Blackwing Rollerball Pen Known almost exclusively for their excellent high grade pencils, Blackwing have now introduced their first pen into their heritage stationery collection. Their rollerball pen has a distinctive half-moon profile that prevents rolling and is designed to sit naturally and comfortably in your hand. The form combines flat and curved surfaces for a controlled grip, while the weight is evenly distributed for a steady feel in use. The pen has a machined aluminium body and a satisfying dual-spring click mechanism. Supplied with a Black Schmidt P8127 ink cartridge, the pen delivers consistent ink flow and has a smooth 0.7mm line. To replace the refill, simply remove the magnetic clicker. The pen is compatible with standard cap-less rollerball refills. Machined aluminium body Half moon profile with anti-roll design 0.7mm tip
