If this is silicone, it isn't working:  NOT stretchy at all
The thing about silicone is that it's stretchy and soft, which is the whole point of a ring.  These are not stretchy at all.  You can tell the moment you open the package.  It's shiny (silicone is usually dull-ish), and there is no give to these rings.  I can see use for the lasso thing, but I'd suggest another brand.  I liked GOLIEF's Silicone Penis Ring 4 Sets, Premium Stretchy Cock Ring for Last Longer Harder Stronger Erection,Pleasure Enhancing Sex Toy for Man or Couples Play.  They were delivered the same time, and they are stretchy, soft, and an assortment.  All fit, so worth the money.
