Selling my Mature Metal Jailbird. The device fit fantastically, but I'm actually having an orchiectomy (balls removed) because I'm a trans woman aaaand this thing requires balls to wear I hope it finds a good home. Bought April 6, 2015. Paid $385. Inner diameter: 1 1/4" Ring size: 1 7/8", oval Gap: 3/8 Length: 1 1/2" Condition is very good. No rough spots at all. Device has been boiled and cleaned thoroughly. Comes with ONE security screw and two keys. MM does sell additional security screws if you lose the one. They do not sell additional keys. Asking $190. Free shipping in continental US. Will ship further if you pay. Will use tracking, of course. I'm in Tampa Florida, if you happen to be local. Would knock $15 off price.
