The innovative "omni-directional" ball of Omni Massage Rollers makes them supremely easy to use while still providing optimal function. Feel less stress and fatigue in your hands and fingers thanks to a comfortable grip that doesn't compromise your ability to detect knots and restrictions in tissue. With the Omni Roller, you can diffuse the pressure for deeper tissue work that's more comfortable for the person receiving. Perfect for home and pro use, you can use it with massage oils or lotions and keep it clean with soap and water. Just remember: never use it on bony structures like the spine.
