The Lovebox sits in your loved one's home and connects to the internet via Wi-Fi. You send your special someone a short message or drawing with the Lovebox app available on iOS and Android. When the box receives the message, an itsy-bitsy red heart spins like a pinwheel. The heart continues to spin until your main squeeze lifts the lid to read the message on the diminutive display.

There is something precious about a tiny little heart on a small wooden cube spinning in silence. It is such a simple hallmark to symbolize that you're loved. When you open the lid it feels like you've discovered a secret message.
