This is a mechanical pencil made with Bonan black persimmon wood. The lead diameter is 0.5mm, and the hardware is made of brass. It's very rare, with peacock figure appearing!! The wood grain is very beautiful. The weight is approximately 33g, although there may be some error due to amateur measurement. It is in excellent condition, but to prevent any problems, please take a look at the photos and purchase at your own discretion. Please refrain from purchasing if you are overly concerned about the condition. If you have any questions, please feel free to ask. I will respond with sincerity. Thank you very much. Accessories include the box and warranty.
