Amazingly useful but terribly uselessUnless your nipples are accustomed to extreme play then this is in no way the item for you. If you're just starting out then look into far milder clamps. If you're into the tough stuff and want that pierced look... well then just get your nipples pierced.
Hold your definitions together for studying on the go. Use it on your mug or wine glass so your guests don't mistake their drinks for yours.
It makes a lovely thumb ring, if your thumbs are big enough. If you're the kind of sex toy enthusiast that enjoys crafting then you'll be happy to know it makes a fantastic removable stitch marker.
You may have figured out my point here, but I'll mention the things that bear mentioning. The packaging is a small plastic clamshell with an insert that isn't exactly discreet. The rings are about an inch across with a loose metal ball. They're made out of some kind of metal, but from the packaging I can only tell you that it's not gold, silver or nickel.
I really want to say something nice about these rings. They look wonderful and in principle they'd be a bucket of fun, but I just can't understand how human nipples can bear them. The longest I lasted was just shy of 10 seconds before they became intensely painful. For weeks I tried putting them on other parts of my body just in case they held some some kind of useful purpose. They were a no go on my bellybutton, still hurt on my fingers and were to too tough to get onto my ears (plus there's better clip-ons out there anyway.) I even tried to see if I could use it as a fake frenulum piercing. That's how much I wanted these rings to work out, that even after causing me unbearable nipple pain I still thought, "well, maybe it could work on my schlong."
In case you don't take my advice then the rings should be easy to clean with soap and water, if they're made of a rust-safe material. If they're not then... well I've got nothin'. Honestly the best advice I can give you is this: if you really want your nipples to look pierced and these rings are calling out to you, then pick up your keys and just drive down to your local tattoo parlor and get them done.
