Your slave needs a reminder of his place… at your feet. Keep him on his knees where he belongs with a Hanson Humbler. The humbler locks in place around his balls and is curved to fit perfectly right behind his ass. Our exclusive hinged design makes application a dream. The custom made snap lock makes for a secure restraint, even when his hands are free. The Humbler will pull on his balls preventing him from standing and keeping him bent over and at your mercy! In order to get the proper size opening you need to determine the thickness of the sack. If you have a ball stretcher that fits, simply measure the inside diameter. If you want a Humbler to use with multiple subjects we suggest buying the 1 1/2 Inch opening. It fits most men. Electrical contacts accept standard banana plugs. Two keys are provided with each Hanson Humbler. Available in multiple wood types and sizes.
