Made from bamboo wood. Measures 22x4". For care and cleaning, wipe with a damp cloth. Cooking grade mineral oil can be used to bring back original shine as needed. Please note: Each board coloring will vary per piece. Some boards may engrave darker than others, but the engraving depth will remain the same due to the same settings being used. * Most of our cutting boards are made outside the US and then engraved/personalized in our shop in San Diego, CA.
