Its a very effective chastity device: place it around the shaft of the penis and during an erection, the points will dig into the most sensitive flesh. As a spiked cock ring: place it at the base of the cock and balls and lock it on with a padlock. As a brutal ball stretcher device: wrap it around the scrotum. The method of torture is up to you! The ring has two rows of 0.25 inch long stainless steel teeth. These are not self-locking rings as you will need a small padlock to secure it.
