Size: Height: Approximately 22cm Width: Approximately 27cm Inside hidden gusset: Approximately 12cm No lining Cotton fabric (about the thickness of a handkerchief) Thin and doesn't bunch up when closing the drawstring, making it easy to use. This is a handmade item. I try to sew carefully, but it is not perfect. There may be areas with backstitching, slight distortions, or uneven dyeing in the fabric itself. Please understand and accept this before purchasing. I will fold it for shipping. I hope you have a wonderful experience.
