I have stored it without using it, so it is unused, but one of the hooks on the right side of the back panel is broken. It can be attached with the other hooks, so I think there is no problem with use, but please check the photos and consider. For those who understand that it is used, thank you. Please refrain from purchasing if you are sensitive. I have a dog. Those with allergies, please be careful. I will be listing while working. Replies may be delayed. Thank you for viewing m(_ _)m
