This one was picked just because I like cards on chips.
For those that don't know what I mean by "card protector" a card protector is used to prevent your hand being fouled while playing poker. You place the protector on your cards to prevent the dealer from taking your cards before the hand ends or from another player from fouling your cards when they fold their cards. Having your hand killed by either of these two actions can be expensive. I know from personal experience. An interesting card protector can be a good way to start people talking which makes the game more entertaining and profitable with some careful listening.
