This all in one head harness gag with blindfold makes for good slave training. The harness is all leather and has 4 straps. 1 strap goes over the head, 2 around the head and 1 chin strap. The inside of the blindfold is soft cotton for a comfortable fit. The gag can be removed so the blindfold and harness can be worn alone. The ball gag is a respectable 1.5 inches in diameter.
