Abstract (en)
A multifunctional pen comprises an outer shell (1) having at least one partition (3) in its inner space, which separates the inner space into two chambers (a,b), at least one of which is to be filled with working fluid directly, thus increasing the volume of working fluid. At the external ends of both chambers writing, drawing or working tips (2,5) are provided. The working fluid filled in the second chamber b may be used to write and draw on the surface of materials, on which writing or drawing with a common ink or the like is not possible or may be used for correcting writing or drawing errors.
