Approximately 15x15 cm. Short length. It's convenient because I don't have to roll up long sleeves every time I do housework. Because it's a short length, it can also be used by children. The elastic is tied loosely. Please adjust it and use it. (After adjusting the size, please tie it tightly) Mini pouch It's a small pouch. How about for earphones, candy, or eye drops? It doesn't take up much space, so it won't be bulky in your bag. We will offer a discount for bulk purchases, but it's just a small gesture. #Pouch #Shimaenaga (Japanese bird) #Medicine #Earphone case #Eye drop pouch This is handmade by an amateur.
