Write directly on these personalized cards, even during the rain (use pencil for best results)! Markings stay put no matter the conditions until you erase or clean with alcohol wipe (required for permanent marker). The factory markings never wash away or fade. Save time and stay focused on the field of play, not your notes! These durable, long-lasting, write-on cards eliminate the need for a booklet or even paper. When a situation occurs, write directly on the card without the need to open a booklet and/or straighten some paper that might be getting wet. The cards allow you to keep more attention on the game, have less hassle with your notations, and enjoy personalization for a professional touch. *Coordinators and assignors!
