Totally Bamboo’s Extra Large Greenlite Utility Board is ultra-lite, super strong, and totally "green"! It is 3/8 of an inch thick, which means that it’s maneuverable and easy to store. It’s also durable; it offers tri-ply, cross laminate construction with a specially formulated high temperature adhesive. What more, this beautiful board is made of strong, eco friendly bamboo. The benefits of using bamboo are numerous. For example: bamboo is 16 percent harder than maple, yet easy on your knives, 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! What more? This board is easy to maintain and dishwasher safe! Use Totally Bamboo’s Revitalizing Oil, after each wash, to extend the life of the board and keep it looking beautiful. Extra large: 20.5 X 14.5 X 3/8”.
