This is a knife box! You can fill it with dry white rice (it takes A LOT) and store your kitchen knives in it. The rice allows you a lot of flexibility in terms of knife size and shape, and absorbs moisture. There's a piece of cork at the bottom so your tips won't touch the wood. Thanks everyone for all the love and great guesses, obviously we can make any size dovetail box- as a planter, for file storage, records, kitchen utensils, wine, etc, just get in touch!
