In the past I have already been lost several pens, because the retaining clips were not suitable to hold the pen in the Jackettinnentasche. And some of these clips were holding so tight set, that it was difficult to spread it for plugging with your fingernails. The LAMY Pico has not even such a clip. But he is at rest so small and round that it can easily disappear in the Jackettaußentasche. In addition, the mine does not look in front, so that nothing can be smeared. Because he has rounded forms, he remains hang anywhere; no retaining clip, in which something might get caught. If you want to write to him, give a short press on the upper pin head and even the dwarf grows to a "real" pen, which fits comfortably in your hand. Only the thin line the supplied Mine (LAMY M 22) is a bit disturbing. All in all I am very happy to have discovered this great dwarf and would no longer put him on the love out of hand.
