Everything you need to call Bingo in one convenient pack. Each pack includes a cage, marbles numbered 1 - 90 and a check tray to keep a record of the numbers you have already called. Cage measures 9" (approximately 23cm) in diameter and stands 30cm high. Marbles are multicoloured and measure 18mm in diameter each. These premium quality marbles display the numbers sealed under a perspex cover to prevent them from rubbing off.
