Thank you for viewing. This is a 55cm exercise ball, perfect for balance and stretching exercises. It comes with a hand pump. For users 150cm-165cm tall. It has been stored folded. I inflated it for the listing and confirmed that it doesn't leak air. There are some minor scuff marks in two places. Please check the photos. I have inspected the item before listing, but there is a possibility I may have overlooked something. Please refrain from purchasing if you are looking for a new-like item or are very particular about details. Returns are not accepted.
