These wood and epoxy products are individually handmade over a period of a week at a time and may vary a little in dimensions.  If you use a board with epoxy in it as a cutting board try not to cut on the epoxy as it will dull knives very quickly.  They will last decades if proper care is taken in their use. They should never be soaked in water or put in a dishwasher.  Each one is soaked in mineral oil and then given 2 coats of Grandpa Mike’s Wood Butter (mineral oil, beeswax and coconut oil) prior to completion.
