The Valcambi CombiBar is the best ever produced multifunctional bar in the world. It is technically designed to serve as an investment bar. The Combibar has been dubbed a "chocolate bar" because pieces can be easily broken off by hand into one gram pieces and used as payment in emergency. The main adventage of the CombiBar is that it can be easily transported and costs much less than buying 50 one gram bars.
