The sensibility is on writing implements such as ballpoint pens, Mine holder or the like. In which the mine can be pushed back and can optionally be replaced by another lead that writes in a different color.

The essential task of the charge is to create a writing device of this type with a simple and inexpensive construction, which is particularly suitable for the various practical possibilities of use.

The writing implement according to the invention comprises a number of uniform retractable pencil leads lying side by side inside a housing in which they are biased upward by return springs. The upper bearing of each mine has a head, which is accessible from the outside through a lateral opening 1a of the housing and has a stop shoulder and a notch arrangement, both of which
