Type of writing instrument: Rollerball I enjoy collecting stationery, and I bought this about a month ago, but I'm selling it because I haven't had a chance to use it! I've stored it in a dark place at home, so there's no sun damage. It's unused, but please understand that it's an old item. This is a vintage pencil made by the company that preceded Kaweco. For those who want to buy it but find it too expensive, how about trying this one? (Referring to the 590 & co. pen) Retail price: 9900 yen Brand: h&m gutberlet Material: Ebonite Sales unit: Body only, ink not included. Auto C300 series refills can be used.
