OPTP Rumble Roller

OPTP Rumble Roller contains specially designed "bumps" that are firm but flexible, much like the thumbs of a massage therapist. The RumbleRoller is waterproof and is also molded with an antimicrobial additive that stops the growth of bacteria. As the user roll on the RumbleRoller, the bumps continuously knead the contours of your body, stretching soft tissue in multiple directions to help restore flexibility and bring relief to common types of muscular pain.
