Great pin, not so expensive, I like gel pens anyway. This slide really well over the paper - but it protects. It collects all four copies that I have tested so far, relatively fast ink at the top and around it, so you sometimes fairly decent color brings to paper - which of course can not dry as fast and in addition thicker lines also like blurred times , I hope that I just caught just a bad batch (the blue ones are great!), Hence four stars. Otherwise I would be due to the smearing three. Oh, and the shelf life is so-so, although I have quite a lot written lately (exam preparation), but the first has not even held by one month. Is in gel pens but probably always the case that they do not keep as long as pens.
