First of all .... these are no Faber-Castel-pins! Until they are really smear-proof passes ever one-two minutes ,,,, and as a form (I really need these pins for documents) recently when opening a bottle of sparkling water on a drop got the font, the font dissolved ... they So are not waterproof. I give 2 stars for the nice letter with the stylus, it does not drip and is easy to hold. But I think it's not good that is sold here under a false name brand on Amazon.
