The spring is great, the filler slides without scratching and scraping across the paper and is very comfortable to hold. The build quality is top, the plastic feels very high quality, the finish also acts like that. Keep very pleasant from the form factor ago, with stable metal spring on the cover for the pin holder. The cover snaps on a tired and precise pen.
I am completely satisfied, I still think the filler but very expensive ... It is, after all, only to a spring, two injection-molded parts and a metal clip. Nevertheless, I would strike again.
