Like most wishing objects this grants well wishes, but the wish is always interpreted in a way that will humiliate someone. For example wishing to go to school, could result in you being naked when you appear at school. Also you can't unwish anything, once it's granted your stuck in your situation. (Based on a storyline in You Are What You Wish)
