WILLY RING 3-Pack super-stretch cockring, use ‘em single or stacked or layered. 

They also stack for gradual ball stretching, add more WILLY’S when you want more stretch—slow steady gradual stretch really works! WILLY RING is a new Oxballs favorite—WILLY’s are 3 rings made from our toughest Flextpr™ (not cheap PVC that breaks after one use). They are the right size, the right stretch, the perfect size.
