For over 10 years I use this model every day. Of course it is not lady-like for small little blocks in the purse. But it is so well in hand that I want no other Feinminenstift more. The mechanism is also after many years as the day - unfortunately this is not self-evident. The clip is pretty unbreakable and should he nevertheless times are carelessly handled roughly, to buy that even for little money. The grip rubber retains its shape even after 10 years - not like some coolies in which the rubber at some point turns around the pin, because too much plasticizer is volatilized. The Radierereinheit is not only convenient but also high quality - mechanics as eraser. The only drawback: the unit is very loose and may have the slight pulling out of a pocket or strap replace. If they then also be lost, which is very unfortunate. As could certainly improve a little.
