POLBAN Hip Seat Single Shoulder Black This is the main body and the single shoulder strap, which was purchased separately. I rarely used the single shoulder strap after I bought it. It was used less than 5 times. There are no major stains on the hip seat, but please understand that this is a used item. Thank you. Shipping will be via Rakuraku Mercari Bin or Yu-Yu Mercari Bin. No individual sales or price reductions.
