Previously I wrote with small ink rollers of Herlitz in which you can insert normal pen cartridges. Actually quite funny and resources. But unfortunately this scribe run regularly on the front of labyrinth if you subtract the caps (vacuum when pulling?). Before then the notes one has already smeared fingers. For business use, a no-go. So now (unfortunately) but again disposable commodity, but it works. A local office trader offers this 5-Mitsubishi pins at the same price in a blister pack, umgelabled of Farber-Castell. I buy locally so happy, but at three times the price for the choice 5erPackung was negative. The pins themselves are well in hand and write very pleasant. In the color I see a hint towards turquoise. Is absolutely not tragic, but the classic royal blue it's definitely not.
