As with most handheld masturbators, the Rimi Tight Butt is a small tubular structure that is designed to accept the penis. Where some masturbators are large enough to accept the entire penis (Fleshlight, Tenga Flip-Hole, etc.), the much smaller Rimi Tight Butt is in the category of Pocket Pussy. Pocket Pussies are sort of a mini masturbator by design but the Rimi is one of the smallest I have ever seen. This device is four inches long. Not four inches insertable, no no. Four inches total. You will note that the accepted length for use is four and a half inches. To fully use Rimi, the user's penis has to breach the far end of the masturbator and be drawn back in.

The observant reader will also note that Rimi is shaped like a very small quintuple amputee. While I found it an odd design choice, I more importantly found it annoying to keep a good grip on. The odd stumps and bumps did not offer a very good gripping surface and the problem was exacerbated by lube. People with an interest in sex with fairies or very small people with no arms, legs, or heads may be interested in this toy.

That soft, slightly tacky material Rimi is made of is TPR, a material that is pthalates and latex free. While it is body safe, it cannot be sterilized the way silicone can. TPR is a bit too soft to be boiled clean so please use soap and water or an antibacterial toy cleaner. As you would expect a masturbator to be, Rimi is soft and squishy, almost no firmness at all. Items this soft make me nervous because it seems like all it would take to reduce it to a puddle of toy-destroying goo is a little harsh language. It reminds me a little of those goo filled tubes you could buy in malls that would fly out of your hand when you squeezed them.

There are some ridges along the inside of the toy, not quite as textured as the diagram on the side of the box leads one to believe but they are there nonetheless and feel pretty good. As always with a handheld masturbator, you must use a good bit of lube. I like Silicone lube for these since it doesn't dry out nearly as fast as water based lubes, though it is harder to clean up. I advise against using any oil based lubes or Crisco or anything. Those are fine if you are using a real ass, but those lubes will wreck the TPR material in this toy.

As stated above, rather than being a simple tube shape, the Rimi Tight Butt is shaped like a tiny woman. While it lends visual diversity to the toy versus other Pocket Pussies, it makes the toy a bit harder to hold on to. The novelty of having sex with a very small person may be appealing to certain users however. I personally think the size of Rimi is a bit too small. While it is made of very stretchy material to accommodate penises larger than the actual toy, forcing the penis against the end of Rimi is not particularly enjoyable and it made me feel like this toy was not designed for me. It works fine as a masturbator for the end of the penis and some of the shaft but you should not expect to get your entire penis into this toy. If you wanted to press the issue though, Rimi is more than stretchy enough to do pretty much whatever you want.

The Rimi is made of that delightful material known as TPR. That means you are going to need soap or an antibacterial cleaner to make this toy safe for storage. I use regular supermarket antibacterial kitchen wipes and those seem to work just fine. You can wash this toy in water but make sure it is not boiling since TPR can't handle the same high temperatures Silicone can. For the same reason, it is not a good idea to put this toy in the dishwasher. Just clean it out manually and you'll have no issues.

When storing Rimi, I recommend putting it in a ziploc bag for two reasons. The first is that the material is a bit tacky and can easily collect dust and lint. The second and far more important is that TPR reacts badly to certain materials. It would be an awful shame for you to open your toybox only to find that your six dollar Rimi masturbator has melted all over your hundred dollar (insert favorite toy here) and ruined both of them. You want to keep unlike materials separated in your toybox, particularly when they are of low quality like this one.

The moment I looked at this box I knew I was going to have a problem. I did some quick math and while I am no measuring scientist, I was still able to come to the conclusion that since the box was barely half the length of my penis, whatever was inside would likely not be the entire length of my penis. I am both happy and disappointed to say I was correct. As other reviewers have mentioned, the packaging has anime designs covering the outside. While that is delightful and colorful, one thing bothered me. Along the side of the box are the three girls that represent the "Nice n' Tight" series. The rightmost girl is the heavyset pink haired girl Rimi with the "Tight Butt". The other two girls, a blonde and a brunette no doubt represent two other orifices that are assuredly just as tight. What bothered me was upon close examination, all three girls were drawn by different people. None of them are in the same style and while it's admittedly a small thing, it's visually jarring and is basically clip art. It tells me that California Exotics cared so little about what this package design looked like, they just grabbed whatever three unrelated stock anime girl pictures they could find and slapped them on there. On the plus side, as usual Cal Exotics describes the product on the side of the box in seven different languages, allowing me to add "Masturbator" to my limited command of French and German.

There are a lot of great masturbators out there and I regret to inform you this is not one of them. Even so, for the low price this one goes for, I suppose it's not terrible. Just remember you get what you pay for.
