This is a UV, insect, and mosquito net for strollers. When not in use, it can be folded up and stored in a pocket for compact portability. It has rubber and hooks on the sides, so it can be secured under the stroller. I bought one, but I ended up using a hand-me-down first, and my child outgrew the stroller before I could use it. Size: Free size, with rubber Condition: Unused, without outer packaging Stored at home As the mosquito season approaches, and for cooler weather trips to the park, this will be useful. It's convenient to have one to protect your baby. Thank you.
