Abstract

Connectable writing instrument composed of two component writing instruments of the same configuration. Each of the component instruments comprises a body, a holder section adapted to hold a pen component at the front end of the body, a front reception hole arranged parallel to the holder section, and a rear reception hole arranged in line with the pen component or with the front reception hole and an engagement projection at the rear of the body. The holder section and the engagement projection engage with the front reception hole and the rear reception hole, respectively, or vice versa.
