Nipples are where these babies belong, but because the sliding ring on the "tweezers" makes these adjustable, you could get adventurous so long as you make sure to adjust the pinch slowly. And remember, clamps feel the most intense right after they've been taken off and the blood comes back to the area pinched.

Good for beginners because they're adjustable, but if you're an absolute beginner, I suggest testing the pinch generated on the web of your thumb first. For me the hardest part sometimes is sliding the metal rings up past a certain point to tighten them, while some skin is in the tweezer part, can be hard. Sadly, not enough different kinds of breasts were available to test nipple size and clamp grip. But they worked fine on me, and I'd say I have smaller nipples.

The metal chain does have a nice amount of weight to it, although the blue coating seems a bit cheap; as I've used the metal slider ring, the color on the tweezers has rubbed off. The rubber on the ends of the tweezers is comfortable and usually sticks well to skin, so go ahead and tug on that chain!

I like the design; it's basic and easy to understand. The toy is relatively easy to put on (adjusting might be a bit hard) but easy to take off. Figuring out how to use nipple clamps can take awhile too, each nipple is different.

This won't vibrate nor transmit vibrations too well, though it will jangle. And well, as for stimulating...

Usually wiping them off with a soft cloth will be okay. If there are body fluids that have gotten onto the toy, you should wash gently and dry right after since these are metal.

The packaging clearly held a sex toy and came with no instructions.
