Nagasawa Kip Leather Pen Case for 1 Pen, Large Size

This is a pen case for fountain pens from Nagasawa Pen Center. It holds one pen.
I purchased it new and kept it stored without using it.
It is in beautiful condition.
The overall color is black, and the stitching is blue.
The length is approximately 16cm, and it is a size L.

I am selling it to organize my stationery.
Thank you for your consideration.
