Sider's Woodcrafting Cutting Board Finish is made right here in our kitchen. It has two ingredients, beeswax and mineral oil. All of our boards are treated with this finish to help protect the board from drying out and to highlight the smooth feel of each board. The microwave safe container holds 6 oz. The Finish can be applied with a clean cloth at room temperature, or heated up. For mor information, please see our blog post "Taking Care of Your Wooden Cutting Board" from August 14, 2018.
