The Sport-Thieme Cork Foam Roller: Made from natural raw materials - The Cork Foam Roller is a very hard and particularly shape-stable fascia trainer. The material of the 30 cm long roller is sourced from the bark of the cork oak tree. Particularly practical: the tree is preserved, as it is not damaged during the bark harvesting process. Multiple harvests of the valuable cork bark are therefore possible. The natural material is also recyclable and odorless.
