Blue Non-smudge Ink Classmate Octane Plastic Ball Pen

Because of its lightweight body, non-smudge ink, and easy glide nip, this pen is great for everyday use. After a few days of use, the pen in particular is compact, elegant, and comfortable to grip. The pen is composed of plastic and has a fine ball bearing at the tip that rotates against a cartridge filled with semisolid ink, rolling the ink onto paper. A ballpoint tip consists of a freely wandering "ball," a "socket" that holds the ball in place, small "ink channels" that supply ink to the ball through the socket, and a self-contained "ink reservoir" that delivers ink to the ball. The ballpoint and tip are made of plastic. Polystyrene, a mass-produced, moderate plastic, is used to make the pen's barrel.
