IT'S OKAY ... LOCK IT, TOSS OR DROP IT!
Only the BILL-BOARD® drop cards are precision die-cut to interlock. You do not need to worry about it opening prematurely or butterflying open when dropped or tossed. You fold it over, lock it, and drop it. It's the only drop card on the market with this must-have feature.
NO BUTTERFLY EFFECT
Money cards (to be considered drop cards) must fold over to "hide" the message inside. TRY IT; Fold a piece of paper in half you will notice it will naturally want to open back up. Worse yet drop or toss it, and it will scoop up the air and flutter, hence the name Butterfly Effect. You don't want that to happen with a drop card. If your drop card opens up and exposes your message, then the entire illusion of found money is ruined!
Our Interlocking BILL-BOARD® money cards prevent premature opening no matter how hard you toss or drop. You can even send them flying like a Frisbee. This is extremely important! It will always look like money no matter how it lands because the inside is never exposed until opened by the receiver.
