Thank you for looking. I made a pouch with a triangular gusset that opens wide with a zipper, using "Kitsune no Komichi" (Fox Path) from "Ten to Sen Moyou Seisakusho" (Points and Lines Pattern Studio). The stitching is done so that the gusset naturally folds when the zipper is closed. This is one of several prototypes and practice pieces. I would be grateful if you would purchase it with an understanding of any uneven stitching or double stitching. There are no issues with use. This is a personal handmade item. It is not a collaborative product or an official product of "Ten to Sen Moyou Seisakusho". Size Main body: Approx. 18 cm wide (excluding gusset) x 9 cm high x 6 cm deep Opening: Approx. 17.5 cm wide x 4.5 cm high Materials Outer fabric: Kitsune no Komichi Felt-like fusible interfacing Lining fabric: Oxford I have a cat indoors. Please refrain from purchasing if you are concerned.
