An easy-grip handle makes the Massage Roller a convenient and effective tool for professionals and home users alike. Knots and restrictions can be felt in the tissue-similar to driving a car over a speed bump-this massage roller allows you to feel what is going on in the body. Never use over bony structures, such as directly on the spinal column. With long-lasting and durable construction, this massage tool can be used in the whirlpool or soothing bathtub, as there are no internal parts to wear out or corrode. For professionals, this product can be used in place of fingers, hands, or elbows.
