Any job well done requires getting your hands just a little dirty. Unfortunately, the soiling of one’s digits is usually followed by a fierce bout of scrubbing that doesn’t always remove the grit and grime to it’s desired effect. If your maximum amount of elbow grease isn’t up to the task, perhaps you should up your intimidation factor and show that sludge what might happen if it doesn’t take notice of who’s boss. Harlem-based design company Spye has just the thing to send quite a fright through your filthy fingertips. Their soap knuckles cast from the genuine brass kind and made from all natural glycerin soap are sure to make that which is unclean glow anew with a sparkly shine…or else.
