Since [[1949]] ''Faber-Castell'' also began producing ballpoint pens, and in [[1950]] introduced a torpedo shaped model, called [[Gentleman]] in black or gray pearl and silver. The pen had revolutionary features like a butterfly shaped clip and a particular [[piston filler]] which contained part of the mechanism in the knob, allowing a greatest dimension of the tank; it was made with a transparent body covered by an opaque plastic cylinder with a regular series of etchings that at the same time had the role of facilitating the grip of the pen and allow viewing the ink level.

In the early '60s the [[Osmia]] trademark was no longer used;  a number of hooded nib plastic models were introduced, they were thinner than previous one and marked ''A. W. Faber-Castell'',  with a transparent section for ink level view. The luxury line was called [[Faber-Castell 66|66]], with body in black, red, blue or green plastic, rolled gold cap and gold nib, the mid range models were called [[Faber-Castell Progress]] and produced in three versions: the 77S in plastic with a steel nib, the 55S with silver cap, plastic body and steel nib, the 55G with gold nib. It was also produced a student model called 54VT, because the ''Vest Tank'', with a secondary reservoir usable through a valve.
