I have one spiral #15 for sale. It has been worn one time. This was a custom device as I am not pierced, however could be used for a pierced male. We had an attachment made on the end to keep a penis from being able to extend out past the end. Unfortunately we messed up on the measurements and need to cut our losses while we can. The measurements are as follows: Teste Ring 1-5/8" Id actually measures at 1-3/4" Spiral from back of Teste ring to tip measures 2-1/4" Inner diameter of ring is 1-1/16" Comes with 2 keys. New with adjustment would be $335 Selling for $200 or best offer. If interested contact me at firstname.lastname@example.org. Full offer includes free shipping in the US. If over seas contact me for a quote. By the way I know the teste ring could be re-sized. I am not sure what the fee would be but you could contact Ms. Lori to get that info. Thanks.
