Both the rabbit ring and insertable shaft house a powerful bullet which provides amazing vibration. Just place the rigid semi stretchy silicone ring over the cock and balls. The rabbit stimulator will tickle and thrill her clit while the ridged dildo penetrates her anally as you pleasure her with your cock. The vibration will travel from the ring into you as you thrust. The premium material has a smooth matte finish that feels as good as it looks. Requires 2 AAA batteries not included. Shaft measures 6.5 in. long insertable 1.15 in. diameter. Ring is 1.25 in. diameter unstretched.
