A new way out of the crisis: Konstantin Slawinski modernizes the piggy bank with the help of SL22 DUELL! The inscription below the two slits in the box turns it into a duel. One against the other. Cinema versus restaurant. Or saving versus spending. Or new handbag versus shoes. Every cent counts and the box with a partition in its middle shows in a playful way who is leading or which dream can be fulfilled first. One thing is for sure: SL22 DUELL makes saving fun again!
