This 7.5" square x .5 thick multi-wood cutting board is beautifully handcrafted by local Connecticut artisan Ed Fay. The woods are a mix of quarter-sawn white oak, rock maple, cherry and black walnut. It's durable, unique and so practical, you'll be reaching for it every day! Exclusively ours, it is not recommended for the dishwasher. After washing a few times, we recommend a treating with mineral oil. Wipe it on, let it soak for an hour or so and wipe off excess. Since every board is lovingly hand-made, there will be slight variations in design, pattern and thickness with each & every one. This cutting board will last forever!
