Blue Roller Pen UB-200 (8)

The roller pen uses Uni Super Ink technology, which is resistant to fading, moisture, alcoholic 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. Due to a special technology, the rollers withstand typical rapid pressure changes that occur during flight. This is achieved thanks to a special reservoir in the body that compensates for pressure fluctuations between the pressure inside the pen and in the airplane. When the pressure onboard decreases, the air in the reservoir compresses, bypassing the tip, preventing ink from being pushed out of the pen.
