These toys are classified as penile sleeves. You can either use it with your partner or alone. It can fit over a penis or over a dildo to add a new feeling to it. This set can be enjoyed by both beginners and advanced users.

The material used in these sleeves is called Senso. It scores a 2 on the safety rating scale used by EdenFantasys. It does have a nice soft feel to it, but that means that it can attract hairs and other things to it. The three sleeves are the same in size but different in texture, each one being unique. The extra texture is supposed to add to the stimulation, but in this case it made zero difference.

There are 3 sleeves in the set. One has little spikes on it, another has raised studs, and the last one is the combination of the two. The sleeves are designed to fit an average guy/toy. If you try to stretch them out too much, they might get warped or torn.

The sleeves are advertised to add extra dimension to your sex life by adding "sensuous stimulation during penetration." In reality it's quite disappointing and not stimulating. I would go so far as to say that the extra texture takes away from the experience because you can't focus on the sex.

The toys have to be washed thoroughly after each use due to the material used in the manufacturing process.
The storage process is also a bit of a hassle. They have to be stored separately in a dark place or else they will melt (yes, I did just say melt). I left one out, by accident, on the side table in the bedroom and it melted in the suns rays (middle of winter mind you). The other two melted together while lying in a bag in the closet where we keep all our toys...

They come in a white transparent box. Each sleeve is located within its own plastic sleeve. I threw all the packaging out right away, but apparently some of the other users on Eden keep the individual sleeves that the Senso rings come with and use it for their storage.

The rings did not add AT ALL to the experience either for me or for my partner. They actually made it more awkward. We tried these things both for me and the toys, in all cases the outcome was identical.
