Thank you for viewing! This is a handmade clip-type pen holder. It's made from domestic Roroma leather. This leather ages beautifully, so the color will deepen and develop a luster the more you use it. The white marks on the leather are wax. The wax will blend in and disappear with use. 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 very close to this size may be difficult to insert and remove. Color: Clip part: Gold (plated) Leather: Purple This listing is for the clip part only; the notebook and pen in the photos are not included.
