This toy was definitely designed
Personally I enjoy these clamps they give you a range of control over your partner that can't be matched. This is likely because the design of the clamps is such that, as you pull on the short loops at the back of the clamps the end attached to the person tightens. This makes them great for hanging weights and even just teasing your partner. The textured rubber tips make these clamps grip the skin firmly making them less likely to slip off creating that very unpleasant pinching sensation that accompanies unwanted removal. Design benefits include a smaller stature and self tightening grip which allows these clamps to be used easily on other sensitive areas as well as nipples. If your partner is more interested in genital play these clamps will attach easily, albeit tightly, to the labia or scrotum for an added sensation rivaled by little else. The metal construction makes this toy durable and capable of holding the added force exerted by weights or simply pulling.
Being a firm believer in the philosophy that you wouldn't try something on someone else that you hadn't experienced I put these on various areas, and they have a real bite. Testing how well they held up to pulling and tugging was an interesting experience, if the clamp had a decent hold of skin it was extremely difficult to remove them without unclamping them the proper way. I have yet to test exactly how much force/weight is require to accomplish this feat and its not a test I look forward to. I have experienced a range of partner reaction to this product. The first time they were used my partner was unable to get enough, her only complaint was that they made her nipples sore the following day. However, that night they made great suggestive devices for how to move and what I wanted. Another partner that I used them on said they were a little much for her. So as a side note, be very careful as to who you use them on and take the first couple of applications slow.
As far as care for these little babies goes, you probably shouldn't be getting them into much so just make sure they stay dry. If the hinges start to stick then you might want to look into some oil. But I have owned mine for a couple years and they still work just like the day I bought them. So all in all there is little maintenance required. Though you may want to keep an eye on the rubber tips on these clamps if they start to get a little thin you might want to think about getting a new pair, because the little cushion they provide is often much needed.
These look scary and complicated to me, as far as nipple clamps go. The rubber tips don't really show up on the photo.
Yeah they are white and have textured "teeth" on them so on a white background they really don't show up all that well. But they do lessen the sensations compared to other metal alligator clamps.
