The Claw will open you up like nothing else. Pinch all four wedges together for a more manageable penetration. Once past your sphincter, it will expand. A hole at the base of the plug allows your partner to peer into your anal depths, or even fill you up with a dildo, an enema, or anything else. The phthalate-free material is firm, yet flexible and will press against all the right spots. Measures 4.5 in. long, 3.5 in. insertable, 2.25 in. diameter at widest point when closed. Center hole measure 1.5 in. diameter.
