This is an escape prevention gate for cats. Due to moving, this is for those who can complete the transaction by December 20th. This listing is for a limited time. I plan to hand over the completed product, so please contact me if you can meet in or around Kameari or Matsudo City. For those who wish to have it shipped, we will handle it with the recipient paying for shipping. It is clean and can be used without any problems, but the middle screw has been attached incorrectly and is on the opposite side (see photo 5). Therefore, if you are concerned, you will need to reassemble it. Please be aware of this. Thank you. I am also listing another set of the same product.
