This is a set of 3 differently-shaped silicone butt plugs that are so helpful for figuring out the sort of shape you like, especially if you've never done much anal play before. You could theoretically use them vaginally; they are silicone and so you can sterilize them, but there are probably other toys better suited for that.

All three toys are silicone, so they have no discernible smell and don't retain any kind of smell once they've been used or stored. All are fairly firm, but not rigid. The slender tips are all flexible, and if you squeeze them they have a little bit of give, but they definitely hold their shape while in use. The pink toy has bulges that give you a little bit of texture stimulation, but the other two toys are pretty smooth overall and just have lightly different shapes.

I don't like really big toys personally, but even so I wasn't a huge fan of how very narrow the tips were on these toys. They're designed that way for easy insertion, but, in my opinion, they don't really need to be QUITE that narrow, and it feels a little unnatural, like you're being poked. It's not uncomfortable per se, just not very pleasurable. The short, thick black one is the only one I still use from time to time, and usually only as a lead-up to using something slightly heftier.

These are nice in that they're very easy to insert, and they're not too intimidating. You can thrust with them a little, but they're not very long so they're best to just put in and leave for a while.

Silicone is always the way to go, I almost always buy silicone toys because you don't have to worry about bacteria. You can just use water and antibacterial soap (which is what I do) or put them in the dishwasher if you want, there are no electronics to worry about. Silicone does pick up some dust, but just rinse it off before you use it and it'll be fine.

All three toys came in a sealed clear plastic bag, nothing special but it gets the job done, and easy to throw out if you're being discreet. There aren't any instructions, but then the usage is pretty self-explanatory.

I can see how this set would be great if you're anxious about trying anal stuff, especially since they're bright colors and not very phallic shapes, so there's no intimidation factor, but even though I was a beginner when I got them I was really enthusiastic so they were a little underwhelming for me. I used the purple one once, the pink one maybe three times, and the black one I still use off and on, but I've generally moved on to bigger and better things.
