Swiss Nathalie Staempfli designed two ingenious soap dispensers that turn a soap bar into beautiful little soap flakes. One version attaches to the wall and allows you to use it with one hand. The other version is a grater that can stand by itself. It can be placed in the same way as a shower gel or shampoo.
Soap bars are more concentrated than liquid soap which has an ecological benefit: You don’t transport water around the globe and they only use paper for packaging. The solid blocks can easily be piled and allow a greater space efficiency during transportation.
This invention already made my week: Soap Flakes.
