Yoga Works Yoga Block L Size, 2 Pieces - Brand: Yoga Works - Material: Cork - Quantity: Set of 2 - Size: L Approximately 22.5 x 15 x 10 cm 1050g I received these as a gift, but I haven't used them at all, so I'm selling them. They were reportedly only used at home. They are stored in a well-ventilated, shaded area. There is a slight chip on one corner. Other than that, there are no noticeable scratches. <Hard cork material for supporting poses that put weight on the body> Made of 100% cork, the hardness and substantial weight provide excellent stability, helping to correct skeletal structure that cannot be overcome by simply increasing flexibility. The cork yoga block M, the same size as yoga block A, is a thin type that is also ideal for fine-tuning poses, and the cork yoga block L, the same size as yoga block B, has a substantial thickness that is also suitable for practicing balance poses where you put weight on your hands. The Yoga Works print logo in brown is on the front center. Please be careful when handling as it is heavy. <Environmentally friendly natural material> Cork is made from the bark of the cork oak, which has a lifespan of about 200 years. After growing for about 9 years, the cork oak is harvested only for its bark without being cut down, and after harvesting, it regenerates and continues to grow on its own, making it an environmentally friendly natural material that values its connection with wildlife and plants. What is a yoga block: It is an excellent prop (support tool) that supports the flexibility of poses and corrects the individuality of the skeletal structure. The goal is "upper emptiness, lower solidity" - a light upper body and a stable lower body. In poses where it is difficult to maintain balance and you cannot feel a comfortable stretch, using a yoga block to stabilize the foundation will eliminate the strain caused by unnatural postures, allowing you to keep your upper body light. It's a good idea to have a set of 2, as it expands the range of foundation building. Once you get the feel of the foundation, it's time to move away from the block's assistance.
