This looks like an ordinary small bar of soap but it's not.
You leave it for someone else to use and when they wash with it, instead of being clean afterwards it will make them look dirtier because when you wash with it, it makes your skin go a brown/black colour!
Great to use in school, work, and on family and friends! This will make the person who uses it turn a dirty brown/black colour, the more they try to was the dirt away, the dirtier they will become!
These make great gifts.
