This is a wooden-bodied mechanical pencil with a 0.5mm lead diameter. The wooden body is handmade and attached to a modified commercially available drafting mechanical pencil. The lead diameter can also be changed to 0.3mm, 0.7mm, or 0.9mm. The material is Yakusugi flame grain. It features a flame-like undulating grain, a beautiful luster, and the very strong fragrance emitted by Yakusugi cedar. It has a very beautiful finish. Approximate shaft thickness: Minimum diameter: 10.5mm (part where fingers rest) Maximum diameter: 12mm The part where the fingers rest is shaped to be constricted, making it easy to grip and carefully crafted to prevent hand fatigue. The tip is a metal die-cast product for drafting. The body is lightweight, but the weight of the tip creates a low center of gravity, which, combined with the finger fit, provides a very light and fatigue-free writing experience. The finish is achieved through 8 stages of polishing and coated with a penetrating inorganic glass coating. The glass coating protects the wood from dirt and moisture, and has a long-lasting effect. While having very strong waterproof and stain-resistant properties, it does not create a film on the surface due to its penetrating nature, so after complete drying, the feel of the wood remains intact, and you can also enjoy the fragrance of the wood. While preserving the goodness of the wood, if used properly, it can be used for a long time with no maintenance. *Since the inside of the shaft is not coated, please do not submerge the inside in water. Please note that this is a handmade item. It will be sent in simple packaging without a box. We have created it with the utmost care, but there may be minor scratches or imperfections. We are offering it at an affordable price, so we appreciate your understanding.
