Up for sale is my custom Mature Metal JailBird. I recently had another custom device made and I will no longer be needing this JailBird. The measurements are: Oval Ring(the ring that goes behind the balls): 2" at widest/left-to-right First cockring of cage: 1 3/8" Second cockring near tip of cage: 1 1/4" Cage length: 2 1/2" curved downward Gap between cage and oval ring: 1/4" Locking post on top of rings instead of in front of oval ring. 2 Guide pins at top of cage and oval ring. Regular luggage lock hole. Purchased in May 2011. I ordered this with measurements almost identical to the CB-6000s if it were being worn with the #1 ring/the biggest ring that comes with it, and the shortest spacer that comes with it. Very comfortable fit The JailBird will be boiled and sanitzed with antibacterial hand soap before it is shipped. Will ship next day after payment has been made. Shipping and handling included/no charge. Asking $275, but will take best offer. IM me or post on here if you are interested or have any questions, thanks! Pictures: http://imgur.com/a/SH9nw#4
