The 3-piece bamboo cutting board set includes three cutting boards. Boards measure 9 by 6 by 3/8-inch, 12 by 8-3/4 by 3/8-inch and 15 by 12 by 3/8-inch. Don't be caught again without an extra cutting board. 3/8 of an inch thick means that these boards are maneuverable and easy to store. Made of strong, eco friendly bamboo. They're also durable; they have a tri-ply, cross laminate construction with a specially formulated high temperature adhesive. Each piece is distinctively attractive, super strong, and totally "green" The benefits of using bamboo are numerous. For example: bamboo is 16-percent harder than maple, it’s naturally anti-microbial and it’s eco friendly; it holds the promise of a sustainable, cost effective, and ecologically responsible alternative to the widespread clear cutting of our old growth forests. Totally Bamboo uses organically grown Moso bamboo, so you need not worry about harmful pesticides or fertilizers. Plus, this bamboo is not a food source, or a habitat, for the Giant Panda. Totally good for you and totally good for the environment! Boards are easy to maintain. Wash with warm water and use Totally Bamboo’s Revitalizing Oil, occasionally, to extend the life and keep them looking beautiful.
