This is a handwood ebony burl wood mechanical pencil. The lead diameter is 0.5mm, but it is compatible with the PG-METAL mechanism, so you can change it to 0.3mm by purchasing commercially available parts. I am selling this because I rarely use it and would like to send it to someone who will. This mechanical pencil is made with a focus on a low center of gravity, achieving both a satisfying writing feel and ease of writing. The ebony wood grain is also beautiful, and the craftsmanship is superb. I am sorry, but I am not considering lowering the price. Thank you for your understanding. Type: Mechanical pencil body Body material: Wood barrel
