This slender erection ring is made of soft, stretchy material that expands to fit most, trapping blood into the shaft of the penis and creating a pleasurable, longer-lasting erection. The tiniest of micro-bullets and a cute clitoral stimulator provide remarkably powerful vibration for such a small size and quiet operation. A remarkably discreet toy for a wild night of passion! Requires 2 - 1.5v button batteries (included).
