Inspired by ItoIto-san's videos, this is a flat pen case made with a Nordic-style fabric. It has a pocket on one side and I think it's very easy to use. The zipper is blue-gray The lining is light gray. Size: Height: Approximately 18 cm Width: Approximately 7.5 cm There is no gusset. The pocket depth is approximately 9 cm. This was made by a handmade enthusiast using a home sewing machine. I made it carefully, but since it's handmade by an amateur, I would appreciate your understanding.
