These little beauties came in a lovely black satin drawstring bag and individual resealable bags. This I think makes it very easy to store and not lose any pieces. These would make a fantastic gift for someone special. The bags contain each clamp and a chain to dangle and add pressure. They are Metal, so they will be easy to clean and store safely. They should also be pretty easy to manage for humans with sensitive skin.

The design is simple to understand. Just twist the screws out to allow enough space for the erect nipple, and then tighten each screw as evenly as possible to allow for an even hang. If you can get some kind of raise from the nipple, these are pretty easy to use. Although if you are a flatter nipped human, it may be much harder to get them to latch on. They are quite heavy, they feel about a 1/2 gram of weight in each. Add in a movement from the chain, and you have a lot of intense sensation. So if you are sensitive to weight, they may be a short-term ware item.

The screw in design can be a lot more intense of a feeling the side pressure clamps. Seeing as the twisting action of the screws can be felt against the nip skin. I find these to be very nice for training because you can gradually increase pressure. They are made of metal, so they are very temperature conductive. So if you want to add some sensation to your play, you can get them cold. The will warm up with body heat, but that can take some time. In all this is a great addition to the toy box of a nipple play enthusiast or anyone training, but might be a bit much for beginners.
