Thank you for viewing! ^_^ (Size) Gusset: 9.5 cm Height: Approximately 10 cm (excluding the gusset) Width: Approximately 12 cm Measurements are taken by a amateur. Please understand that there may be slight variations. Adhesive interfacing is applied to the outer fabric, and a domette core is sandwiched between the outer and inner fabrics. How about using it as a coin purse or a small item case? It's convenient for storing keys, lip balm, candy, etc. It's also recommended as a gift for friends! This is a handmade item by an amateur. I try to make it carefully, but there may be some distortion, wrinkles, and small scratches on the gusset from the time of purchase. If you are concerned, please refrain from purchasing. I look forward to hearing from those who understand handmade items. #SmallItemCase #CoinPurse #Strawberry
