Most bingo sets come with a flimsy piece of cardboard with holes punched in it to hold the balls you draw to call the numbers. Cardboard deteriorates over time and with use, and the cheaper the cardboard, the more difficult its going to be to use as it continues to fall apart. This set of ball holders changes that. The large size means you dont have to worry about precision accuracy in where you place things, its never so crowded that youre going to dislodge other balls already placed on the board, and the cups ensure that none of them are going to accidentally escape in any event. The numbers to tell you where to put the balls are easy to read even at a quick glance. Once you use this holder once, youll never want to go back to flimsy cardboard ever again!
