Magnetic Knee Support, Mixed Poles

This tube-shaped supporter uses a combination of north and south magnets. South is used to stimulate, which is useful in cases where you want more blood flow to the area. (Not recommended for injuries, as south pole energy can make them worse. See north-pole knee support if you have an injury.) Slips over the leg to support the knee and surrounding area. Made of stretch nylon/elastic/acrylic with cotton lining, it has 32 1,000-Gauss ferrite magnets sewn inside. Tan color. To determine your size, measure circumference of knee when bent at a 90-degree angle. Small: Medium: L: XL: 10 1/2" long and 15" in circumference when stretched
