OSSUR Prosthetic Leg, from all the information I could research it’s composed of carbon fiber and titanium. The company OSSUR is one the leading custom prosthetic manufacture that only uses the best components available. I’ve taken as many picture as possible of the height, the outer circumference and as best of the inner circumference of the leg. All you see of the item in the picture is what is for this sale. Please feel free to as any question.
