These are nice and thin. Seniors can hold many in their hands while playing BINGO. They cover the large 8.5x11 BINGO card numbers. Because they are thin, it is more difficult for dexterity to pick them up off the table, but my Seniors love them, keep them in bowls, grab a handful, play BINGO, pick up the BINGO card and slide all chips back into the bowl, and start all over again.
