Given the breathability and the inherent oils in the bark, bread will not dry out or get moldy as rapidly as in plastic or metal boxes. It is recommended that you put a layer of paper under the bread in these boxes. Easily cleaned with a damp cloth, and in cases of serious, may be cleaned with detergent and hot water. No dishwasher, please. 12.5” x 5.5” x 8.25”
