Fully customizable as to the level of pinch, Lux Fetish's Bell Nipple Clamps grip tight to chosen erotic areas, thrilling with inexorable pressure. Tipped in softer black rubber, the high quality metal Clamps tighten easily with a twist of a screw up top.  A pretty black bell bead attached to the end of each swings tantalizingly with movement- the tug of the clamps will intensify naturally along with movement as they dangle and dance. Clamps adjust to .6 inches (1.5cm) wide, easily fitting most.
