• Intense Testicle Cages: These metal eggs have several screws that can be turned using the allen wrenches provided to tighten and increase the pressure on the testicles. After the metal egg closes, tighten each one individually so they can have equal pressure against the testicles.
• Bondage Bar: The metal bar keeps the eggs together so you can pull at it and pull at the scrotum and testicles evenly. Add a weight to the center O-ring to add a ball-stretching pull to the testicles, as well!
• Lock and Key: The metal eggs have a swivel closure. Close the egg around the scrotum and testicles, fold the hinged screw between the two curved bars, then screw it tight. This will reveal a small hole in the pin where you can place a lock. Use the lock and key to lock the eggs into place!
•  Egg width: 1.65 inches, length: 2.4 inches, Pin Spikes max length: 0.8 inches, Spacer for scrotum: 0.36 inches.
