Leg Massage Roller.

Product manual:
The 12 trigger point foam rollers made of high density foam work independently of each other,
resulting in deep tissue stimulation and myofascial release.
Density: Made of high-density EVA foam, unlike other plastics, to avoid unnecessary pain or bruising.
Surface Texture: The surface of the panel wheel is textured. Spiked foam rollers create varying degrees of pressure.
Shape and Size: Great for on-the-go
