The Fasermaler of Stabilo are very high quality and above all, they never last very long and dry actually. After my professors have these pens recommend us as an entry pens for the first base character classes in Arhcitekturstudium I was surprised to only. But in hindsight, I can understand this completely and can only recommend it. Before approaching expensive pens of professional brands buys Once this test. So just to be recommended and as already mentioned in the title not for children to draw, are also ideal for writing since the peak is quite stable and not as fast as in Platt cheap felt tip pens. 5 Stars!
