Dog Circle Woody System Circle Natural Easy to assemble, just put it together in a square and insert the pins from the top. Size: 90cm x 60cm, Height: 60cm, Entrance size: Width 33cm, Height 42cm. I used it for about a week, but my dog didn't like it very much, so I'm giving it away to someone who will use it ^ ^ It's in good condition. However, since it is a used item that has been inspected by an amateur, I would like to give it to someone who can trade without any claims or returns.
