Thank you for viewing. This is a black stroller under-bag. I bought it to go to a theme park and used it for one day, but I don't need to keep it on, so I'm selling it. It can hold a lot of things, such as outerwear and luggage. Please refer to the 6th image for the size. If you attach the shoulder strap, it can also be used as a tote bag. You can fold the stroller with it attached. It seems you can also attach it to the side of the stroller. Washing Stroller accessories Stroller bag Storage bag
