Thank you for viewing! This is a net to prevent dogs from jumping out of their playpen. I'm selling it because I'm not using a playpen anymore. I got it as a set with a playpen when I got a dog, but I only used it for about 1-2 days and then stored it at home. It has a zipper, so you can open it and pick up your dog from the playpen. If anyone has a playpen that this size fits, please consider it. ◎Shipping Method It will be shipped via anonymous delivery. Please note that the shipping method may be changed between Rakuraku Mercari Bin and Yuuyu Mercari Bin. Thank you for your consideration. *
