The tiring process of washing your hands
If you consider rubbing a bar of soap on your hands strenuous, you’re pretty weird.
But hey, at least you’ll love Vibrating Soap! It creates its own lather by vibrating in your hand.
Obviously, the makers know their potential customers well because the description includes this:
“One of our favorite aspects of this bar of soap is its incredibly delicious scent that smells good enough to eat, but please don’t eat it, only use it to wash!”
Another important feature: 100% safe to use in water.
That's a plus for any kind of soap.
