These are great for anyone looking for serious nipple clamps with a seriously playful flair!
They are tweezer style clamps, with rubber coating on the ends to protect sensitive skin from real damage, and screws to allow the user to customize just how hard they pinch.
This design seems to work quite well overall. The screws allow for great control over how much pressure is applied and the rubber coating ensures (relative) comfort.
I would not recommend these to anyone unsure about whether they're interested in pain. For those just trying this out, go for something less serious, because in order to really stay on during any movement (and especially pulling) they need to be clamped down tight and needless to say, that hurts!
These are not really discreet, anyone who knows what a nipple clamp is will be able to tell what these are right away, but they are certainly easy to store. They don't take up much space at all and can easily be tucked away into a bag, or other small space.


Here, you can see the box, one clamp in the plastic packaging, and the other out of the packaging. Please do excuse the poor quality, I think my camera was having a bad day...

These clamps are almost entirely metal. On the box, it indicates "Main composition: Iron" which would certainly explain the weight. There seems to be no indication what other metals are present here, but these clamps are made from latex-free, non porous, food grade materials. I am confident that these pose no material related safety issues.
The metal is all smooth and cold to the touch, as metal often is! It quickly warms to body heat if pressed against the skin.
The rubber on the ends of the clips feels like.. rubber. There's nothing special about it! It's smooth, with some drag to it, and just forgiving enough to provide a marginal level of comfort during wear.

Basic specs:
Total length- about 10"
Length of chain- 7"
Length of hatchet- 2"
Length of clamp- 1.5"

While I generally like the design, I dislike some of the ways it was executed.
The tweezer style with the adjustable screw is great and very user friendly, and I just love the hatchets, but I find it overall to be heavy and clunky.
The chains connecting the clamps to the hatchets are massive! This makes them perfectly strong and absolutely sturdy, but being all solid metal, they just end up so very heavy.

I do still like these clamps and would recommend them to those who are interested, but if I were remaking these, I would do a few things differently;
The clamp design itself is fine, no problems there.
The chain should be somewhat more delicate and smaller. Certainly not as small as a jewelry chain, but this is approaching the size that a dog's chain leash could be made from. I think the size is just unnecessary for nipple clamps, and it adds too much weight.
The hatchets could be smaller, but that's not a real issue. Were I to design them, I would likely choose something more lightweight. Solid iron is simply too heavy for comfortable nipple clamps.

As for the fit, I find that they work reasonably well on my large nipples. These should fit fine on any size of nipple, so long as you can take the pressure needed to keep them on- again, they are quite heavy and I find that they want to fall off unless tightened a lot.

These are quite easy to figure out, and to put on/take off. The screw mechanism is straightforward and I find it quite easy to screw and unscrew.
Beyond pinching, I don't find these to have other functions!

These are quite low maintenance. Being almost all metal, all it takes to clean them is a quick wipe down with a cloth or paper towel, damp if needed (be sure to dry them after if you get them wet).
In addition to being easy to clean, they are also easy to store. The original box can be used to store them if you like, or they will easily fit into a small bag, or can be tucked into a corner somewhere. These really won't take up much space, so I'm sure everyone will find a perfect place to keep them.

These arrived in a sturdy, glossy cardboard box. It hasn't ripped so far despite multiple openings and closings, and is pretty compact, so it works well for storage. However, the box is definitely not discreet, so keep that in mind.
Inside the box, each clamp and its attached hatchet were in small plastic bags, which were easy to open. The clamps were ready to use right out of the box, and due to the sturdy material I don't think anything would hurt them in the packaging (or out of it!).

These were my first set of nipple clamps. Having never used them before, I wasn't 100% certain just what to expect, but they turned out to be just what I thought- painful!
Of course, that was a perfectly fun time for me, so I certainly recommend these to anyone interested in causing pain to themselves or a partner.
As you may have gathered, my one big gripe is the weight of them. They are so flippin' cute, but they are SO HEAVY! At times, I would prefer to have less pressure applied, but that means they will absolutely slip right off if I move around any! I may actually find a less weighty chain to replace this one with in the future.
