POLBAN ADVANCE Hip Seat (with Single Shoulder) I purchased this about 4 years ago and used it until around this spring. While there's a general feeling of use, I think it can still be used. The Velcro on the waist is worn out. There is some fuzzing on the Velcro parts. It fastens with a large buckle, so I don't think it will affect use, but please refrain from purchasing if you are concerned. Regarding the single shoulder, I haven't used it much, so I think it's in good condition. I am not considering selling the items separately. Box and instruction manual included. The single shoulder will be stored in the front pocket, and the shipping label will be attached directly to the box for shipping. I am selling this because my child has grown. This hip seat was very helpful for our family. We had two, and both my husband and I would use them when we went out. The hip seat was convenient, and it was easy for both of us to share and adjust the size. I hope it will be useful for someone else's family as well.
