A&E's 24-box design for 1 -day or 2-day meets. White, easily color-coded by you for any course so there is no need to buy a large number of different colored cards. Just "fan" a stack of cards and with a waterproof marker run a stripe of desired color down the left edge; and then do the same at the "turn-in" stub end. Packet of 50 cards. Heavy Card Stock (perforated stub).
