The y-style clamps are, in my opinion, good for beginners and great for masochists and experienced clamp users. They're incredibly easy to use, clean, and store. The clit clamp is hard to get to stay on for me, so I detached the clit clamp from the others and attached the nipple clamps to a collar of mine. Those stay on really well! I've also had them used on my pussy lips, which was definitely fun and interesting.

The clamps and chain are made of metal, while the tips of the clamps are coated with a softer kind of plastic material. The chain measures around 32 inches in length, which I found to be plenty of length to reach everything. The metal is smooth and doesn't scratch the skin.

The clamps are extremely easy to use. They're tweezer style clamps, with o-rings that you slide up the clamps to pinch them closed. The design makes it so that you can have them barely pinching or completely pinched together, depending upon you or your partners pain tolerance and desire level. They're easy to put on and would fit most all sizes of nipples. I have larger nipples myself and they can fit around them just fine. It's easy to wear, and reaches all the spots it needs to reach, but I wouldn't say "comfortable" simply because... well, are nipple clamps even supposed to be comfortable?

Care and storage for these is a breeze. They're mostly metal, so a damp cloth or toy cleaner will clean them right up should they get dirty. They are also small so they can fit anywhere to be stored!

I really enjoy these clamps. You can adjust the pinch on them easy from a light sensation to "you're ripping my nipples off!" Being a masochist, I tend to go for the extreme and these deliver if you adjust them the right way! I could not get the clamp for the clit to stay in place on me, but that could be due to my own anatomy and not a design flaw.
