Cork is a 100% natural and fully recyclable material and is made from the bark of the oak tree. It is also a hypoallergenic material, resistant to mold and does not rot. In addition, the oak tree, where the bark is harvested, will produce new bark, which in turn can absorb new CO₂. At GOYOGI, we are very proud of our cork collection and have both blocks, rollers, balls and mats in the delicious and strong material.
