Dark Blue Roller Pen UB-200 (8)

The roller pen uses Uni Super Ink technology, which is resistant to fading, moisture, alcohol solutions, and acids. The writing quality of the roller can be compared to that of a fountain pen. The body of the roller and the... removable cap with a clip are made of high-quality plastic. The transparent grip zone allows you to monitor the ink level. It is particularly worth noting the reliable Japanese assembly of the roller. Thanks to a special technology, the rollers withstand typical rapid pressure changes that occur during flight. This is achieved by a special reservoir in the body that compensates for pressure drops between the pressure in the pen and in the airplane. When the pressure drops on board, the air in the reservoir is compressed, bypassing the tip, without forcing ink out of the pen.
