Writing at the university very much and just had the snout full of these cheap pens. Even a ballpoint pen for 4.95 at a local dealer wrote unsatisfactory. THEN I got from a friend this Kulli. WOW! No more interruptions while writing! One can also make points that you see and if you take a longer line draws a Linial, saut these pens also not! The ergonomics could be improved a bit ... But the typeface is so great, because I can only give full star number!
