Thank you for viewing. I purchased this for rehabilitation of contracted muscles due to a wrist fracture. I am selling it because I no longer need it. I think there isn't much sign of use, as I have only used it a few times. Multi-functional training equipment, with rubber rings compatible with 30LB and 40LB resistance, and support equipment. This is a used item, so please refrain from purchasing if you are looking for perfection. Please consider carefully before purchasing. We do not accept returns or refunds after purchase. We apologize for the inconvenience.
