The RingO Ranglers - Cannonball ring is a simple and effective penis ring designed to enhance sexual pleasure by trapping blood in the penis to maximize the firmness of the wearer's erection and help delay ejaculation. The Cannonball has a thick construction and a no-slip, no-roll design, with prominent raised bumps lining the interior and exterior to offer even more sensation. Made of lab-tested body-safe SEBS, the Cannonball stretches to fit almost any size, and is compatible with both water-based and silicone-based lubricants.
