Back to 2009, we started exploring sustainable materials. We developed RPET microfiber pouch, lens cloth and facing materials for the eyewear cases. We also used PLA materials to replace the common plastic inserts used inside the soft or semi-rigid cases. It is recommended Eco-friendly materials such as cotton, linen, bamboo fiber, wood and RPET materials are used in the design and development processes. We are the pioneer of the industry in the development and utilization of ecological materials.
