Please read the profile. This is a denim backpack for small dogs. I bought it because I thought it was cute, but I never used it and just kept it stored away. The size is approximately (measured by a layman): 17 cm tall x 14 cm wide x 3.5 cm deep. The pocket has a zipper that can be opened and closed, but it's a decorative pocket and not a separate one. The shoulder straps are adjustable, and it can be put on and taken off with buckles, like a harness. It's new and unused, but it's a used item that has been stored at home. Please understand that it will be compressed for shipping, and wrinkles may occur during that process before purchasing.
