Washing up can be such a dull and repetitive task. Now instead of just scrubbing down with some plain bar of soap, you can have soap in the shape of brass knuckles. Sure, you’re getting far less soap for your money, but it’s just so much more awesome. It’s made of all-natural glycerin soap. For $15 you can get two of these brass knuckles through Spye Design. Sadly, right now these Soap Knuckles are unavailable.
