This device is very similar to our popular penis jewelry plugs but it comes with a penis head harness. The harness is articulately hand made. The 2 1/2 inch shaft glides down the very sensitive urethra producing a unique experience. A head harness prevents the plug from going further down the urethra than the actual plug. Penis plug is topped off with a beautiful amethyst stone. Diameter of shaft is 0.1 inches. Diameter of harness ring is 1.25 inches.
