First Impressions:

First, out of the box, these are some very simple nipple clamps. Very straight forward and to the point items with minimal is any instructions really needed. They came in a ziplock type plastic bag and were labeled with only a bar code as many items that come from EF are.

Material:

These are made of metal, I'm going to assume stainless steel unless otherwise told since it is very easy to make items out of that and their lightweight but durable feeling nature. They are obviously cold to touch but get warm in your hand or when held or placed on a warm surface.

The grips on the tips of the clamps are rubber. This is not only to help grip the nipple or whatever another area you want to put them on but also to protect it from the hard and possibly sharp metal surface. If you notice these slipping off, they can easily be placed back on and possibly superglued into place to ensure it doesn't happen and cause a possible problem or bleeding.

Fit:

They are an ok shape; however, not the best for those with larger nipples like myself. Personally, I tried them on and regifted them after realizing they are much too small for myself, but that's alright. I recommend doing the skittle test. If your nipple is as large as or larger than a skittle, I suggest moving along unless you are truly into a very tight or possible lack of pinch in these depending on how far you want them stretched open.

The clamps themselves are very easy to pinch and hinge nicely at the midpoint. You can use the screw to leave the clamp as loose or tight as you want, which is fantastic for those who want the ascetic and feel but don't want the actual "pinch."

The chain is a good length and weight. Not so much that it will pull the clamps off if they are too loose but enough to have some weight there that you feel a little tug when worn.

Performance:

They are holding up very well for my wonderful friend, and they've told me that they use them at least weekly. Minimal to little wear and tear is showing. Since my friends are newer to the scene and sex toys, it's fantastic to know they are working so well for them, and I absolutely say as long as these fit right, they are very beginner or any level friendly! From what I've been told, they haven't adventured into using them on other parts of the body yet, but can't wait to give it a try. I absolutely suggest trying this out with your favorite clamps. You never know what fun may come out of it!

Care and Maintenence

For care and maintenance, I recommend a damp cloth with mild soap. Not too much and don't allow it to stay too wet because I'm not 100% sure on what it's made from, and it may cause rust.

Do remember that Rubber is a porous surface, and using them on naughty bits makes it a little risky.
