Tiger Tail USA Has Really Found The Answer To All Of Your Questions About Muscle Rolling! Turn sore muscles into happy muscles – fast! Every person deals with some degree of muscle soreness – even if it’s just from doing yard work or sitting in a chair. This is what makes The Original Tiger Tail such a great personal wellness tool. It was created for both the couch potato, with achy muscles from inactivity, as well as the most active person on the block. Tiger Tail massage tools provide relief to your muscles and in turn improve your overall well-being. If you’re wondering how to choose between the 18″ and the 22″, the only difference in construction is length. The 22″ offers four more inches of massage surface. The 18″ offers 10″ of massage surface while the 22″ offers 14″ of massage surface. Each handle is 4 inches long. The 22″ is best for buddy massage and back massage and for people who are less flexible or larger in size. It works well for personal use but the extra length does make it easier for using on someone else. The 18″ is our best-selling size and works great for personal massage. The shorter length makes it just a little bit easier to pack into small bags.
