Experienced pens may have small defects or scuffs, since they often have been pre-owned, and they have been priced accordingly. All Japanese Pen Nibs are graded as the manufacturer intended, that is, they will be finer than western counterparts (e.g. Japanese Medium is more like a Western Fine, Fine is more like an Extra Fine, etc.).
