Starting with the original Locking Trainer Ball Gag design (which features a locking, black leather strap and a non-toxic black rubber ball mouthpiece), we have added a dildo ring to the front of the gag, which gives you the option of strapping a dildo on to the front.
The nickel-plated ring is 2" in diameter, and it attaches with snaps. This ring size will work with most dildos, as long as they have some kind of a base on them (for example the balls on the typical cock-and-ball dildo).
For very large or very small dildos, it is also possible to subtitute different-sized rings. Dildos and larger/smaller rings are sold separately, not included. The ball gag is usable with or without a dildo strapped on the front.
