The cutting board is crafted in Sweden with untreated birch. Wood is a living material that must be handled with care. For durability, a new cutting board should be treated before use. Apply a good amount of food-grade oil and repeat the treatment several times until the surface feels saturated and no longer absorb oil (about 3-5 times). This treatment should then be made occasionally during the cutting board's entire lifetime to prevent cracking. When the surface starts to feel worn-out after a few years of use, take a fine sandpaper and sand the surface lightly. * Dimensions: 44.5 x 20.5 x 1.8 cm * Material: Birchwood
