Blackroll - Blackroll Twister Black - The BLACKROLL TWISTER is your new secret weapon in fascial training, adding a new training tool to our line of foam rollers for the effective treatment of fascial adhesions. The TWISTER is relatively small and easy to transport, so it can be with you every day. Its effects on fascial treatment, however, are immense. The special knobby surface of the TWISTER and its ergonomically precise convex shape make the novel, point-by-point stimulation of the tissue and fascial adhesion possible.
