I ordered these fillers after a lot of thinking for everyday writing in the classroom. He sits comfortably in the hand and is very light so that you can continue to write even without fatigue even after several pages. The F-spring has a pleasant flow of ink and does not scratch. It is also not yet come to Anschreibfehlern, while she writes soft and you need little power, just as it should be. The one star I am afraid to pull off yet because the Safari compared to barely more expensive alstars but feels quite cheap. I assume that he will hold still long and do his service ... I have this time but then decided to go for a safari, because the alstars are relatively prone to scratches.
