A gel pen is a special form of a ballpoint pen that uses an aqueous gel as ink instead of an oily paste. The gel pen consists of an ink-containing tube of polypropylene, which opens into a metal tip and is usually held in a shank. To prevent ink from drying out, the ink column is closed by a silicone plug. Capped caps have a gasket for the tip, while pinch-type gels contain a coil spring in their tip which, when not in use, seals the ball against the end of the tip. The rotary movement of the writing ball produces so high shear stresses at the boundary to the ink column that the ink is liquefied and can be ejected similar to an ink pen. The resulting ink flow is five to ten times that of a ballpoint pen, whereby the writing ball is very well lubricated. The country with the largest production previously was Japan. In recent years, China has established itself as a major manufacturer of cheap gel pen.
