ABSTRACT:
A pen having a holder (10) and a mechanism (11) arranged in the pen, comprises a substantially hemispherical writing end and has such a mass distribution that its centre of gravity is located between the crest of the writing end and the meridian plane of the substantially hemispherical writing end, such that the pen, when put e.g. on a table and having its nib (12) retracted, will automatically rise so as to stand substantially on the crest of the writing end when in its resting position.
