The bitterest chocolate is produced in limited amounts (net weight 30 g)
Color coding was developed for the chocolate series. Moreover, additional coding was used to differentiate bitter chocolate bars from milk chocolate bars by embossing the packs of the former in silver and the packs of the latter in gold. A very insubstantial volume of foil is used for that.
A variety of sorts (net weight 108 g)
The new series of packaging for mini-bars was developed by overhauling the former design.
