I have a dog pen or what ever you want to fence in. It is about 20 foot long and about 20 foot wide. I think it is 6 or 8 feet tall, comes apart in four pieces. has and full size entrance door. I have it on my car trailer which is 18 feet long and it hangs off the end. The only thing it needs is new pins(bolts) to put it back together. My sister used it for a few years and no longer needs it and I do not want it laying around. So I am asking 350.00 or best offer.
