How does it work?

A buyer receives a chocolate bar with one square missing.
Online, the buyer chooses who should receive the square.
The missing square becomes a personal gifting experience.

What is it good for?

Turn part of the product experience into a personal message and an act of gifting.

Evidence & sources

Contemporary reporting describes a plan to produce 13 million bars. This is a production quantity, not a sales or participation outcome.
