This is a Karin (Japanese quince) mechanical pencil. The lead diameter is 0.3mm, but it's compatible with Pentel Stein leads, so you can change to your preferred lead size like 0.5mm or 0.7mm by purchasing commercially available leads. You can feel the appeal of the wood, with a mix of white and black Karin wood. I'm sorry, but I'm not considering lowering the price. Thank you for your understanding. Type: Mechanical pencil body Body material: Wooden shaft
