A magnetic tak set with from quality ingredients and top notch craftsmanship. The acrylic diamonds are called water and they really set this board off. This is one of my best looking boards in my opinion because of how all the ingredients come together. The grid is an ebony inlay. The game pieces are stored in a felted chamber when the board is not in use. I finished the board in semi gloss polyurethane and wet sanded to perfection. The game pieces are birdseye and walnut. The board measures 12 inches square by 2 and a quarter inches tall when opened. Tak is a registered trademark of cheapass games and all licensing fees have been paid.
