No, the backgammon pieces in this set are not magnetic. Instead, they are crafted from Uria Stone material, which is known for its exceptional durability. These checkers are designed to withstand extensive gameplay without breaking, scratching, or cracking. The size of the checkers corresponds to the dimensions of the board, so for the 18-inch (45.7 cm) board, the checkers are 1 1/4 inch (32 mm) in diameter. While they don't have magnetic properties, their quality and construction ensure a reliable and enjoyable gaming experience, and their size is suitable for the specific dimensions of the board.
