This salt and herb box is made from one single, solid piece of maple. It represents the kind of skilled craftsmanship we think is rare and that we're proud to offer. It's finished with mineral oil to prevent drying or cracking. The handcrafted construction makes it unique and uniquely resistant to odor absorption and staining. That means you'll enjoy it in its originally intended condition for years and years and years. In other words, it's a true keeper.
