I bought it for the office, since the (metal) Rotring 600 0.5 seemed excessive for everyday use. It replaced a Faber-Castell TK-Fine 0.5 that "ate its bread" and I was impressed with the quality and comfortable writing. You feel it sturdy even though it's made of plastic. Fortunately, it has nothing to do with the old Tikky pens where the finger contact point was hard and wavy, resulting in fatigue during continuous use. To cut it short, an affordable, beautiful, comfortable, and functional 0.5 mechanical pencil that, combined with the amazing Rotring HB leads, redefine pencil writing.
