The Yi Salad Servers are made from solid, handcrafted Kwila. Kwila is a naturally red hardwood that is native to Australia. The servers are slightly oiled with a natural, food safe oil to help them repel any access water that they may come in contact with during the serving of food. They should not be washed with any kind of detergent but simply wiped clean with a damp cloth and placed in a well ventilated place during storage. Available through our store.
