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 blue in color with each roll measuring 2" by 16.5 ft.
