POLBAN Advance Hip Seat with a single shoulder strap. I only used it for a short period after purchasing, so it's in very clean condition with no noticeable scratches. It's very convenient for toddlers who are starting to walk, as you can easily pick them up. The size is adjustable, so both parents can use it! It also has a little storage space, which is very convenient. Although it's in good condition, it is a used item, so please refrain from purchasing if you are concerned about minor scratches or are very particular about condition.
