While a liquid soap dispenser is very convenient, a good old solid bar of soap is a much ‘greener’ option, as it’s more concentrated and doesn’t require a plastic bottle. But squishy, wet soap bars next to the basin are a pain, and they harbour bacteria too. So, what to do? Young designer Nathalie Stämpfli has come up with a very satisfactory solution with her Soap Flakes soap holder. It takes an ordinary bar of soap, and shaves off tiny soap flakes every time you want to wash your hands.
