Library cards (or, if you like, customer cards) on heavy weight 30 mil YELLOW PVC cards. Cards include incrementing barcode numbers (eg. "001", "002", "003", etc). Email us your own logo. These are the most affordable cards of this quality you will find. Only 35 cents per card + shipping (100 cards per order)(NO SETUP FEE). This is approximately half the price that other companies charge (and they won't print cards in small quantities like we will). We have the needs of your small school library in mind.
