It was a true dream piece, this my.pen until I dropped it and it fell into a crack between the wall and gym floor. There he will live together with other fillers of inferior quality that just expire constantly slip out of hand and are simply ugly. But he, just the my.pen, it will show everyone just as he showed me. Pelikan, Faber Castell, everything worked out, but he here, the my.pen, he kept his ink on the inside and never slipped from the pen. I've made a big mistake trying to replace him after losing against an online pen. After months of bad luck with the online pen, I decided to get myself a new my.pen. And what should I say? Each copy of this filler is a gem! It was not just a stroke of luck with the time I have lost, oh no! Each my.pen has the same excellent features! Thank Herlitz, thanks for the first filler that does not manage to run out! Thanks!
