These are Lumi-chan and Jinko-chan, front and back respectively. Interfacing is applied to the outer fabric. The lip balm is for size reference. Uses a YKK 16cm zipper with a ball pull. ■ Size: Approximately 12cm (height) x 17cm (width), no gusset. Please understand that there may be slight variations. This is a handmade item by an amateur. It is not perfect like a mass-produced product. I try to sew carefully, but there may be imperfections such as curved seams, fabric distortion, and misalignment. We appreciate your understanding. ☆★☆ This product is a handmade item by Amy using fabric from 고양이삼촌 (Koyan Isamchon). It is not an original product of 고양이삼촌 (Koyan Isamchon).
