36" tall lightly used exercise pen. Measures 48" x 48" but can be set up in any configuration you want. My dog can jump out of it so I am in need of a taller one. It was used for a puppy as an alternative to a crate. It would work well for another puppy as an alternative to a crate or to keep them out of trouble when you can't watch them 100%. I do have other puppy supplies which I can include with it. Location: Sterling it's NOT ok to contact this poster with services or other commercial interests mass
