This is a Cocobolo burl wood mechanical pencil from YkU Koubou. The lead diameter is 0.5mm, and it uses KATO 202 gold hardware. The clip can be removed. The orange burl grain is very beautiful and complements the gold hardware well. I kept it in a pen case as part of my collection, but I'm putting it up for sale so someone can use it. It's lighter than a Nohara Kougei pen and thinner than a Koubou Setsuri pen, making it easy to handle. Cocobolo will deepen in color over time, becoming even more beautiful. The pen itself is also made very carefully, is easy to grip, and is a very user-friendly masterpiece. I'm sorry, but I'm not considering lowering the price. Thank you very much. Type: Mechanical pencil body Body material: Wood shaft
