This is a mechanical pencil made of ebony and rosewood. The upper shaft is rosewood, and the grip is made of ebony. The lead diameter is 0.3mm, but since it has the same internal mechanism as the Pentel PG-METAL350, it can be converted to 0.5mm by purchasing commercially available parts. Both ebony and rosewood are considered to be among the three most famous hardwoods, allowing you to enjoy two famous woods in one pen. Shipping methods can be changed, so please feel free to ask. I'm sorry, but I'm not considering lowering the price. Thank you for your understanding. Type: Drafting mechanical pencil Body material: Wooden shaft
