This is the perfect preservative and moisturizer for your wooden cookware or furniture (and even makes a nice hand cream). It is a mixture of beeswax and mineral oil that I make in my own kitchen. It comes in a 2.7 ounce jar, but because of density, when the jar is filled you get a little more than 2 ounces.
Just wipe some on your board, let it soak in, and then wipe off the excess.
A jar is included with every board sold.
If you are local to Phoenix and would like to pick the board up (for free) instead of paying for shipping, enter discount code "LOCAL."
