This plastic play pen was just what I needed.  In fact, I purchased several of them.  I used them to make a long fence to keep my small dogs out of the dining/living room.  Just hooked the sections together with the white heavy plastic pins, arranged them in a semi zig-zag pattern & simple as that, I've got a perfect barrier.  This product is plenty sturdy enough to work as a fence or playpen, yet not so heavy that it cannot be easily moved.  VERY HAPPY WITH THIS PURCHASE !!!!!
