This all black curve humbler is designed to keep a submissive man on his knees, and does the job excruciatingly well.

Made out of two black wood pieces with a carved opening for the balls, the two halves get screwed together snugly over the wearers scrotum. Once the humbler is in place he will not be able to straighten out or stand, if he knows what is good for him.

The ball hole measures 1.5" in diameter.
