This is a ballpoint pen made from jade rough stone from Ootaki, Itoigawa. It is gray jade. (※Although it appears mostly white in the photos, it is a tasteful piece with a pattern of shades.) Due to its delicate construction, please be careful not to drop it on a hard floor. I use it for work, wearing it around my neck with a strap. Also, only the grip is made of jade, and the other parts are ready-made. The ink is also commercially available, so I think you can use it for a long time. Please use it stylishly as your own original ballpoint pen. Since no chemicals such as wax are used, you can enjoy the natural texture of the stone in the photos for a long time. Please consider it by referring to the photos. If you have any questions, please feel free to comment. Jade is by no means cheap, so I would like you to be satisfied before purchasing. Please note that we may cancel your order depending on the timing of your purchase, as we are also selling it elsewhere. Thank you.
