CanDo Kinesiology Tape is made from cotton/rayon fibers that are latex-free and hypoallergenic. This skin-friendly Kinesiology Tape has a wave-like acrylic adhesive on one side that pushes sweat and moisture away from the tape. It can be stretched lengthways by 30-40% and is water-resistant and air-permeable. This means that it does not come off in the shower,pool, or sauna. This case of 10 rolls comes black in color with each roll measuring 2" by 16.5 ft.
