Liquid soap requires much more storage space and thus requires a larger infrastructure for transporting the product to the consumer than a regular bar of soap. Not to mention the oil implications of liquid soap, which makes it much less Eco friendly.
The “Soap Flakes”, as it’s been dubbed, shaves small flakes of soap from the bar directly into your hand for easy lathering, hopefully comparable to that of liquid soap. The designer of the product has ‘eco’ in mind.
There are two version: one that adheres to the wall for hand washing, and one that can be held directly in the hand like a pepper mill grinder. While the latter is much more self explanatory in operation, the other is not. As you place your hand under the dispenser, much like a soap dispenser in a public restroom, you push the lever which activates the grinder.
