We believe when we discuss the sustainability, we must start in various directions. The first, the raw material must be toxin free based on REACH or other chemical requirements around world. Second, the production of each material should be improved and decrease the impacts for our planet. Third, material should be animal friendly, we do not use anything from animal or conduct animal test. Besides, the material itself must be a good solution for finished product. Once lifespan of finished goods is extended, it may help to reduce the wast. The burden of the planet will be reduced. Sometimes, we also need to think about how to deal with those finished goods when they become waste. Among our collections, each of them contributes different efforts on sustainable issue.
