Pentel Fine Rollerball Pen R50
The Pentel Fine Rollerball Pen R50 classic green-barrelled pen has a cushioned nib that provides smooth writing – 0.8mm tip writes a 0.4mm line. Water-based ink writes up to 2,200 metres. The unique writing sensation produced is a combination of a hard alloy tip, set in a flexible delrin socket, with fibre-fed ink to enable writing at any angle. Still one of the most distinctive pens on the market, Ball Pentel is a design icon, and one of the most successful pens in the world.
