This is a sharp lead case from Kobo Setsugi, made from keyaki (Japanese zelkova) wood from Ise Jingu Shrine. I purchased it but haven't had the opportunity to use it, and as it's a lucky item, I'm offering it to someone who will. It should pair well with wooden mechanical pencils, including the Pencil Wedge. The keyaki wood from Ise Jingu Shrine comes from the rebuilding of the shrine, and it's said that it's unknown when more will become available. Compared to typical keyaki, it has a pale yellow color and a smooth feel. The diameter is about 8mm, so it won't take up much space in a pen case. I'm sorry, but I'm not considering lowering the price. Thank you for your understanding.
