I bought this a few years ago because I liked the check pattern. I carried it around when it rained, but I never ended up using it, so I'm selling it. It has hooks in various places, so it might also be suitable for folding umbrellas, but I don't know how to use it. Are the hooks for ventilation? Or maybe it's designed to fold up small for easy carrying. Please see the images for the size. I've uploaded a photo with a 55cm umbrella inside. The opening for putting the umbrella in and out is wide, and the Velcro is also wide, making it easy to use. There are no tags. Thank you.
