🔒 Exclusive (Hidden) Interlocking Tab & Slot

Every BILL-BOARD® drop card features our exclusive hidden Tab & Slot design — a small detail that makes a huge difference. When folded, the two sides align perfectly and interlock, keeping the card securely closed.

This prevents the dreaded “Butterfly Effect” — when lesser cards pop open mid-drop, exposing the message too soon and breaking the illusion of real money. With BILL-BOARD®, your card always lands money-side up, keeping your message concealed until your prospect opens it.

The tab and slot are graphically camouflaged to blend seamlessly with the printed design, disappearing completely when joined — a true engineering touch that separates BILL-BOARD® from everything else on the market.

For the best presentation, gently “puff” your folded card into a slightly rounded shape. This adds a 3D dimension that enhances the visual realism. We’ve even printed a subtle money border inside each card to maintain the illusion if it’s ever partially exposed — another reason BILL-BOARD® remains the most realistic money drop card available.
