Enjoy using this set of 2 fish-shaped salad servers not only for special occasions but everyday - since they are made of high quality, durable acacia wood. Acaciaware is a dense, naturally resinous hardwood that resists penetration by water and will not absorb stains or odors. Just hand wash with soapy water and air dry. Although it doesn't usually require oil, if it appears to be drying out, just use a non-toxic mineral oil to restore it to its natural beauty.
