ABSTRACT:
An ink writing implement has a front part with a writing tip that comes into contact with the writing substrate, and a writing fluid cartridge whose interior chamber containing the writing fluid is tightly sealed before being put into use, and which is connected to the front part during use. There is also provided an equalization system disposed inside a housing and connected by one end to the interior chamber of the writing fluid cartridge and by the other end with the outside air. The writing fluid cartridge and front part are rigidly attached to one another. The front part can be inserted into the equalization system through a back opening and moved into a position in which it protrudes beyond the front opening in the housing.
