Stylish, yet comfortable! The wide elastic straps will accommodate most sizes, and the attractive thong style back design offers snug maneuverability. Insert a flared-base dildo into one of the included metal O-rings, snap it into place, and you are ready. The back supporting strap offers a more form fitting design that hugs the contours of your body, allowing you to move freely. With the interchangeable rings and snap-in system, you can replace one of the included rings for your own, for more size options.
