These little guys definitely do the job of getting your nipples hyper sensitive. You could also use them on your clit, but it it is a little hard to get the suction to work properly down there. I wouldn't suggest wearing these during intercourse, because, well, they look silly. I have the purple variety and they make me look like I have big round purple nipples, which is not the most attractive look. After you take them off they do make your nipples large and erect. Anything rubbing against your nipples for the rest of the day will feel great whether it is your bra, your shirt or your honey!

These are a soft PVC material. It is very smooth and squishable. The texture is nice, there were no seams bugging my sensitive bits. The material doesn't have an icky plastic smell either! I got the purple color, which is nice and not super bright neon purple like the pink appears to be in the picture.

These are a little less than an inch wide and about one inch long. They fit me well. I have very tiny nipples though, I could see how some people with larger or long nipples could have a hard time getting these to work. They are adjustable as you can make the pressure stronger by squeezing more at the top of the bulb while the sucker is on your nipple.

These don't come with any instructions, so they take a little bit of figuring out. They are pretty easy to use once you have mastered the technique, though. You just need to put the sucker over your nipple, make sure it is actually on your skin and then squeeze and release. When you release the sucker will try and suck up more air but will grab onto your skin instead! The suction is strong enough so that they stay put if you are just wearing them on your bare breasts and not bumping them around much. They would definitely pop off if you tried to wear them under a bra or during intercourse. I didn't find the actual pressure of these sucking my nipples while they were on as pleasurable as I thought I would. It was interesting at first, but after a minute or so I mostly forgot they were there. Taking them off lead to more interesting sensations but the really fun part about these was how sensitive they make you after use! The extra sensitivity stayed for well over three hours. Any nipple play would be extra fun after using these!

Soap and water, done! PVC is a super easy material to clean and it doesn't velcro to any fuzz or dust so you don't need to be too worried about where to store them! They are also super tiny so they are really easy to store as they don't take up space. I just pop mine right in my drawer.

These come in a small plastic clamshell. It pops right open without scissors. The package doesn't have any instructions as to how to use them. The card insert says "Mini Nipple Suckers" at the top so it's not very discreet but if you took the card out it is just a clear plastic package, so that could work for storage. The clamshell takes up unneeded space so I'm just going to throw mine away and stick the suckers in my drawer.

These didn't leave any bruise or hickey-like marks on my nipples, which is a plus. My nipples were red and did have a ring around them from the suction for sometime after using the suckers, but it went away within an hour.

This was my first experience using any kind of nipple toy! I really enjoyed these little guys because I love having my nipples stimulated but can only get to one when paying attention to the nether bits! These could take care of my nipples while I take care of other areas. It was a great first experience and I will be trying out more nipple toys!
