Thank you for viewing! This is a handmade clip-type pen holder. It's made from Tochigi leather, made in Japan. This leather has a beautiful aging process, and the color will deepen and develop a luster the more you use it. The leather is thick, so I think you can use it for a long time. It can hold pens up to approximately 16mm in diameter. Pens that are at the limit of this size may be difficult to insert and remove. Colors: Clip part: Gold (plated) Leather: Natural Only the leather clip in the first image is for sale, so the notebook and pens in the photo are not included. Type...Stationery
