(1985)
Designed for schoolchildren, these brightly colored ballpoint pens conform to the elastic movements of the human body. Between the rigid nib and pocket clip housings, is a ribbed portion that flexes with body motion, avoiding breakage when placed in a pocket. The ink runs in a flexible body-conforming plastic tube which runs through the length of the pen alleviating the leaks associated with traditional rigid-body pens. When the pen body is twisted, the lower housing snaps upward to meet the upper housing exposing the pen nib and enclosing the flexible portion in a rigid shell for optimum grasping.
