The pins are in my opinion, after extensive, probing the best on the market.
As other brands simply can not compete (for example, with S start).
Clear these pens cost a little more but that's justified.
On the one hand, the pins are very clearly visible and not only lubricate slightly translucent. Secondly, can the writing very well and almost without residue wipe. (What remains slight colorless shadow, which can be, for example, remove with water very quickly.)
