Abstract: A writing instrument with an operating side, with a writing side with a nib, with a tank which can be filled with liquid writing medium, with a piston, which is movable within the tank, and with an operating element arranged on the operating side for axial adjustment of the piston within the tank. The writing instrument is characterized in that the operating element can be brought by a user from a first axial position, namely an idle position, in which it is held axially in position in particular with locking, into a second axial position which differs axially from the idle position, namely an operating position, in which the operating element has a larger distance to the nib in comparison with the idle position and in which the operating element can be gripped by the user and moved for the axial adjustment of the piston.

Abstract: A writing instrument, having a writing tip and a writing part, which can receive a writing medium reservoir for the writing instrument, and having a removal aid which is releasably connected to the writing part for assisting the removal of a writing medium reservoir, which can be arranged or is arranged in the writing part, which removal aid having a receiving space for a connectable portion of the writing medium reservoir and one or more connecting parts for releasably connecting the removal aid to the connectable portion of the writing medium reservoir. The or each connecting part is configured such that, by the connecting part bearing against the connectable portion of the writing medium reservoir, the removal aid can be connected or is connected thereto by a releasable frictional connection.
