Petio's Dog Room Circle for toilet training. This is only the roof for the regular size. I mistakenly purchased this, even though it's for the small size. I realized this when I tried to install it after opening the package. I put it back in its original condition immediately after opening it, so please consider it as an unused, opened item. Original price: 9,658 yen - Type: Dog Room Circle - Color: Brown Thank you for looking.
