Bamboo sheets and bamboo rug. I bought it on Amazon, but I hardly used it. The following is a copy from Amazon's information. Brand: Ooshimaya Body size: Approximately 120 x 40 x 0.6 cm Body weight: Approximately 1650g Material: (Body) Bamboo, (Connecting thread) Nylon Country of origin: China ● The feel of the bamboo pieces is addictive. ● "Bamboo" items blend in with the surroundings regardless of whether they are Japanese or Western style, creating a space with beauty and coolness. ● "Bamboo" grows quickly, which suppresses the felling of forest resources and is an eco-friendly resource that reduces the burden on the environment. ● You can relax with a refreshing feeling of "minus 2 degrees Celsius body temperature" and a moderate massage effect. [Please note] ※ Because natural materials are used, there may be some errors in size, and the color may vary slightly depending on the fabric lot. ※ Also, when you purchase additional items, the color may differ from the previous ones. ※ As the color changes due to sunburn etc. as you use it, the color will inevitably differ from the new one. ※ Natural material products are not treated with chemical deodorization. Therefore, the unique smell of natural materials may remain. Due to the nature of natural materials, it is not possible to provide a completely odorless product. However, it will gradually ease as you use it for a while. ※ We pay close attention to quality and conduct inspections, but because natural materials are used, mold may occur depending on the environment, such as usage conditions and place of use. When using, please ventilate regularly and dry in the shade in a well-ventilated place to remove moisture. ※ Black spots and brown parts can be seen on the back, but these are attached during the manufacturing process and are not harmful. Please use it with confidence.
