POLBAN Advance Hip Seat Includes a single shoulder strap. I haven't used it for very long since I bought it, so it's in very clean condition with no noticeable scratches. It's very convenient for children who are starting to walk, as you can easily pick them up. The size is adjustable, so it can be used by both parents! It also has a little storage, which is very convenient. Although it is in clean condition, it is a used item, so please refrain from purchasing if you are concerned about minor scratches or are very particular about condition. If you would like to see additional photos or have any questions, please leave a comment. I am also listing this on other sites, so I will prioritize the person who applies to purchase first. Please understand that the item may be removed suddenly. Popular model: POLBAN ADVANCE
