Thank you for viewing! This is a handmade clip-type pen holder. It's made of domestic Roroma leather. This leather ages beautifully, so the color will deepen and shine the more you use it. The white stuff on the leather is wax. The wax will blend in and disappear as you use it. It's thick leather, so I think you can use it for a long time. It can hold pens up to approximately 16mm in diameter. Pens that are just about that size may be difficult to insert and remove. Color: Clip part: Gold (plated) Leather: Black This is a sale of the clip part only, so the notebook and pens in the photo are not included.
