The Anal Thruster's graduated balls allow the user to start off small and work his way up to the maximum diameter of 1.25 in. Made of polished stainless steel, it features 5 ball sections of increasing diameter from 0.75 in. to 1.25 in. and will go in 6 in. when fully inserted. The end is fitted with a T-handle with small attachment holes. The steel is also sensitive to temperature so cooling the thruster before use will add additional sensations. Weight is 8 oz.
