POLBAN ADVANCE POLBAN ADVANCE Hip Seat with Double Shoulder Straps Color: Melange Gray Purchased new in 2022. Used for about a year by my older child, but I mainly used an Ergobaby carrier, so the number of times it was used is relatively few. My younger child only used it about twice. I am selling it because my children have grown and no longer use it. I think the product is generally in good condition, but please understand that it is a used item. There is some fraying on the edge of the inner tag, so please refrain from purchasing if you are looking for a perfect item.
