I made a 0.5mm mechanical pencil with black hardware from KATO202 and a Japanese zelkova wood body. It can also be changed to a ballpoint pen. Gold and silver hardware options are also available, but will be an extra charge. It's hard to tell in the photos, but the real thing is much brighter and sparkles depending on the viewing angle, making it look like a jewel and is very beautiful ✨ Please refrain from purchasing if you are looking for perfection, as this is a handmade item. Japanese zelkova is very sturdy and is also used for the pillars of the stage at Kiyomizu-dera Temple! The maximum diameter is about 12.5mm. A wood cube will also be included.
