Heartwarmers promotional Item for Libra. Apply heat to reveal a message.
This was our attempt to create a modern day fortune cookie. These hearts were overprinted with a heat sensitive ink which, when warmed on your skin or a cup of coffee/tea, revealed a secret message or helpful hint.
We made these here in Australia and they were inserted in packs at our customer's production line. The concept can be applied to other designs or as a promo 'win' mechanism.
