This massage roller uses 3D floating point massage technology to effectively relieve muscle tension and discomfort. Made of environmentally friendly polymer, it feels comfortable and provides a deep, soothing massage without harming the skin. 13 rollers provide 360-degree smooth rolling. The fat roller has a gentle multi-layer structure that gently rolls on the legs, back, and arms. Compared to single-axis rollers, 13 rollers distribute pressure evenly and prevent excessive strain. The ergonomic, non-slip handle adapts to the natural curve of the palm and ensures a secure grip even with sweat. Whether you are working out at the gym or relaxing at home, you can safely and comfortably control the intensity of your massage. This 13-roller fascia relaxation roller is made of elastic material and fits most men and women. Its flexible design allows it to easily adapt to different leg circumferences and body parts, ensuring a personalized massage experience.
