Our foam rollers, back balls and massage balls are not made of cheap plastics. they are made from durable, lightweight, sweat resistant cork. Traditional fitness rollers are typically made of cheap polyurethane that absorbs sweat and bacteria. They go soggy, soft and discoloured over time. Our Cork ball is a better alternative to the spiky balls normally seen in Physio clinics. Our Cork peanut is the better alternative to back balls and our cork roller is a better alternative to muscle rollers.
