I made a pen case by patching together fabric from minä perhonen. The zipper is a 20cm YKK. Interfacing is applied to the entire surface of the fabric. Part of the lining is hand-sewn. The linen fabric has slubs. This is a handmade item by an amateur, so there may be imperfections such as distortion or fraying. This is not a collaboration with minä perhonen. Please only purchase if you understand that this is a handmade item. Due to the nature of viewing images, the product images may differ from the actual colors, so please understand. Returns are not accepted. Please only purchase if you are able to complete the transaction without any problems.
