Thank you for viewing! This is a pouch using a 20cm zipper. It's suitable for storing things like bankbooks and medical record books. It's a flat type without a gusset, so it doesn't take up much space. Soft interfacing is applied to the outer fabric, giving it moderate firmness. Fabric: Seersucker Height: 15cm Width: 20cm Lined with ivory fabric I make each item carefully, but as this is handmade by an amateur, please understand that there may be some slight imperfections in the machine stitching and minor errors. m(_ _)m Thank you for your understanding and consideration. Instant purchase is welcome!
