Thank you for looking. This is a handmade coin purse made by "yasou" from "Ten to Sen Moyou Seisakusho". The bird-shaped clasp is cute. This is a personal handmade item. It is not an official product or collaboration item from "Ten to Sen Moyou Seisakusho". Materials used: Outer fabric: yasou Felt-like fusible interfacing Lining fabric: Oxford Size: Clasp: 12.5 cm x 5 cm (excluding the knob), antique gold Main body: Approximately 17.5 cm wide x 12.5 cm tall There is no gusset, but darts are included to give it a plump shape. Although carefully made, there may be slight distortions in the fabric or stitching, double stitching, or glue overflow. We would appreciate it if you would understand that this is a handmade item before purchasing. Also, we have a cat indoors. We take care to prevent fur from getting in, but please refrain from purchasing if you are concerned about this.
