Heavy duty webbing makes this strap-on kit both a challenge and a pleasure to use. Once everything's properly snapped together, situated correctly, and tightened up, the harness is good to go. A variety of cocks can be attached to this universal harness by slipping them through the chromed ring, allowing ball sacs to hold them in. The kit also comes with some extra webbing, which can be snapped onto the leather dong-holding area, so that the harness can be used on a thigh. Though there are no instructions provided for this retro-fit, it's not too difficult to figure out how to reconfigure the unit just by glancing at the helpful box cover photographs. The kit does not include a dong.
