American Heirloom’s Washington state-shaped cutting board is made from a 100% rapidly renewable bamboo plywood.
Dimensions vary with the edges of the state borderlines. The Washington board is approximately: 14⅜ x 10⅛ inches and ¾ of an inch thick.
The boards are finished like fine salad bowls, with an FDA-approved water based finish. Occasionally rubbing your board with mineral oil or olive oil will preserve it and give it a nice matte finish. The oil will also keep the bamboo from drying and cracking. We do not recommend submerging the board in water or putting it in the dishwasher. A quick wipe with a wet sponge is all the cleaning a well-maintained board needs.
