From its very inception, Kommerkors has been working for Rotring of Hamburg. For Rotring, Kommerkors developed various writing implements, including the “Esprit” series. Rotring was taken over by Parker Pens. Through the merger of the Rotring and Parker brands, this series is now marketed under the Parker name.
These Esprit ballpoint pens are shorter than normal so they easily fit into diaries or trouser pockets. When in use, the pen slides out to a normal length. This sliding system has been patented.
