This cheese/cutting board was made from Makore, an African tree species. The wood was purchased at a specialty supplier in Ontario. The board has been treated with boiled linseed oil, a food safe finish. To clean, wash with soapy water, rinse, dry, store upright not flat and periodically condition the board using a food safe finish such as pharmaceutical grade mineral oil. The board measures 6.25 by 15.5 inches.
