I used it as an umbrella, but the ribs of the umbrella broke down quickly, so I made it into a foldable carrying bag. Size: Folded: Length: 8cm, Width: 11cm Opened: Length: 31cm Width: 29.5cm String (handle): 27cm Weight: 31g It's neither too big nor too small, and it's an easy-to-use size. Since it's made of umbrella material, it's water-resistant and useful.
