Test your masochistic edges with these scrotum CBT egg shells with spikes! The eggs are made entirely of stainless steel so they are durable, long-lasting and easy to sanitize. The metal is also sensitive to temperature so you can heat or cool them for extra sensation! Each egg fits around the testicles and there is a spacer of 0.36 inch width where the scrotal sac goes. The testicles go inside the eggs and then the device closes around the testes using a hinged pin. To lock the testes in place, close the hinge and begin tightening the nut down on the screw. This should reveal a small hole in the pin where you can place one of the two included locks on the pin and lock the egg into place. To add pressure and pain, tighten any of the screws that surround the eggs. To add an even more sadistic twist, add a weight to the small, metal bar that connects the two eggs; attach the weight to the small O-ring at the center of the bar. After use, wash with warm water and soap and spray with a toy cleaner. For serious sanitation, these items can be placed in a dishwasher or soaked in a cleaning solution. Ready to take your devious desires to the next level? As a willing masochist, you can enroll your loving Sadist into kinky play with these stainless steel CBT eggs! The heavy eggs can be made even heavier with the use of a weighted ball. Add pressure and pain to each testicle by slowly tightening the screws. See how it feels to be aroused and on the edge of pain. How far can you go before you reach your edge?
