Thank you for viewing. This item is brand new and unused. I purchased this popular product, but my dog usually uses a wide size, and it seems like the regular size won't work well, so I'm selling it unopened and unused. *Please note that when shipping, the shipping label will be attached directly to the outer box in the photo.
