Anybody looking for a good 'average use' set of nipple clamps will love these. This is another product that I originally bought for personal use, then added them to my everyday line because I liked them so much. These are quality clamps which deliver a p retty intense degree of pressure (for the casual pain fan) when left at full tension. But, the best thing about these is their adjustability. My wife did not originally want a pair as she enjoys a light nipple stimulation and thought these would be too i ntense, but after we got these she was sold. The screws allow you to make very fine adjustments. This is also great if you want to 'ease into' a more intense tension. Just turn the screw a bit and the tension will increase or decrease a bit. This has bee n another good seller for me, and profitable since the wholesale price is fairly low. There is one almost identical competetive product which I have seen other vendors selling (I am not sure who distributes them but SexToyClub does not offer them) which is cheaper, but they look, well, cheaper and smaller. I have sold many of these and customers have had nothing but good things to say about these clamps.
