These rectangular cutting boards are created using 2,000 volts of electricity! Then the burned wood is removed and filled with beautiful crushed stones, pigments and a food safe resin. Each pattern is 100% unique and can not be replicated. Keep this in mind when ordering! You will choose your fill color but the electricity will guide its own original pattern each time! These come in three sizes, Large- 18" x 11"x .5" Medium- 11" x 10" x 1" or Small- 12" x 6" x.5". You can pick up to two colors. If you would like a second color please add to special instructions section of your order!
