Strapit Kinesiology Tape is made of a cotton fabric material with 5% lycra/spandex and the highest grade Japanese adhesive. It is designed to work with the skin and fascia to assist in many key roles including: a decrease in pain and soreness, assisting in the movement of fluid and toxins via the lymphatic system, assisting in healing, proprioceptive feedback and support. The original Kinesiology Tape features a 2 way stretch and can last between 5 to 7 days at a time. It also features a low risk of allergic reaction because it does not contain latex or zinc oxide. It measures 2 inches x 5.5 yards and comes in a black color.
