I’ve only used the nipple suckers for their intended use. I have used them on my boobs and nipples. This is my first nipple-related toy. I wanted something with which to ease into nipple play with toys. They are pretty inexpensive and fun to use. They are good for single times and partnered play. I find that they really do provide a good amount of suction. You could really use it on any area that can hold suction. It’s a pretty strong suction feel that gets more intense the longer you leave them on. There are two basic ways you can put them on: you can squeeze the bulbous end and then place it over the nipple and it will suck, or you can place it over your nipple and then squeeze. I found squeezing then placing over the nipple and letting it suck worked best. It provided good suction and heightened sensation. This is definitely something to try when getting into nipple play. I did keep them on the whole time, which made my nipples really puffy and swollen. The first time, they stayed swollen for a while and even started to hurt a tiny bit on one nipple. If you like swollen, sensitive nipples, you are going to love this.

These are made of PVC, which is a 2 on the material safety scale. They are light and have a shiny, vinyl-like texture--very smooth. They are odorless and don’t have a plastic smell or taste to them. They can be cleaned with a cleaning wipe or warm water and anti-bacterial soap.

The Nipple suckers have a circumference of 3". The base is pretty much the size of a quarter. They are long enough that you won't pinch most nipples when you use them. A little pinch wouldn't be a bad thing if they did since you’re going for a little nipple play. They are 1" long. They should fit comfortably over most nipples. Squeezing the toy generates the suction, so you can get a tighter squeeze when they are on by squeezing the tip again.

The packaging wasn't anything special. It was basically a clear package and that had a place for each nipple sucker. It didn't come with a bag or anything real to store it in besides its own package. That's what I keep mine in cause it fits well but it's not very discreet. There weren't really instructions just kind of trial and error for the best way to get them to stick. They are pretty self-explanatory.

I kept them on the whole time while playing. I did reattach a few time when it because too intense for me. The longer you leave it on the more intense it will be. After using it my nipples stayed swallow for a while but like I mentioned before one of my nipples did hurt awhile after like I would say like an hour or two. I like them a lot because it was almost like a constant pinch but soft at first then harder later. If you already have it suctioned to your nipple and you squeeze again then it will tighten the suction and the tighter you go the more likely you are to have a sore nipple at the end.
