This is the crow repellent net "Karasu no Ami-chan," marketed as a simple solution to keep crows away. It stands firmly on its own thanks to the chain weights. According to the product description, it can hold one 45-liter garbage bag. It's approximately 65cm tall, 70cm wide when folded, with chain weights at the bottom and a drawstring closure at the top. This item was purchased at my parents' house, and it seems they either tried to use it once or never used it at all, but it's in good condition, though it has no packaging. I hope it will be useful to you.
