This is a lovely tray made for carving and serving meats and vegetables. It was cut down from a Sycamore tree in Concord California. Walnut oil finish was used to help protect the wood's character. Clean with warm water, mild detergent, and dry it immediately. It can be re-oiled with walnut oil (found in grocery stores) or mineral oil. Do not use vegetable oils as they turn rancid in time.
