Help players at all levels enjoy the game! Bingo cards are slightly weighted with a thin metallic layer that helps the 2.5 cm magnetic foam bingo chips stay put, so players can use the cards in their laps or at any angle! Large numbers on the cards make play easier for those with visual disabilities, and the write-on, wipe-off surface can easily be cleaned and sanitized. Set includes 25 BIG 21 cm x 30 cm bingo cards and 250 magnetic bingo chips. For up to 10 players.
