Expand the versatility of your favorite strap-on harness with four sizes of rubber O-rings. These moderately stretchy, latex-free rings allow you to affix new and exciting dildos from extra-small to extra-large to your favorite harness.
Alternately, you can choose your ideal size and tightness and use these rings as cock/ball rings. Some people enjoy using cock rings to restrict blood flow and allow for harder, more sensitive, and longer-lasting erections.
