If you're not going to use this as part of a cosplay (costume play) or as a piece of anime art, the best use for the Rainbow Heart is definitely as a dildo. The handle on this is big enough that one could definitely use this without hesitation both vaginally and anally.

However, I would not recommend this as a beginner toy or for someone new to glass. While it's very pretty and very nostalgic, the nubs are extremely intimidating. However, for more experienced users looking for something new, full speed ahead! This is definitely worth trying.

Now remember, since this Heart is made of Pyrex glass, it is completely solid with no give. And thus, when thrusting, be EXTREMELY CAREFUL. I cannot stress this enough, especially since the nubs cover the entire insertable length of this toy. You wouldn't want to be walking funny with something bruised internally!

Since this is made of glass, one could also use this for sensory play. Pyrex glass will retain its temperature fairly well. And if you know how to angle a toy without killing your insides, the nubs also allow for some amazing G-spot stimulation.

Pyrex glass is my absolute favorite toy material. It's firm, so there's no give to it. I'm a sucker for sensory play, and this one is far above the cut. There is no smell or taste to glass, and it won't retain either when washed. The nubs on this one, again, are all over the length of the toy and most definitely add to stimulation when used. However, the texture is not one recommended to beginners because it's probably going to be a little too much to handle.

When I first saw the Rainbow Heart, I knew I had to have it. I was a big fan of Sailor Moon growing up, and this took me back. It was simply never in stock, so it took forever to finally get it in my hands! The design of this toy is extremely cute, extremely fun. If it doesn't work out for you, it at least will fulfill about a billion other uses, especially as a piece of art around your home.

It's a little over 9" long with about 6 1/2" of insertable length. The insertable part is straight and covered with a plethora of rainbow-colored nubs. The rest is a light purple heart-shaped handle. And let me say, while I *love* nubs and texture, I had to take it easy when I used this toy! The texture is quite honestly mind-blowing, but I'm in love with it.

While nobody is really going to question whether this is a sex toy (more of an abstract piece of anime art), I wouldn't call this travel-friendly because of the size. Definitely store it away in a padded bag when taking it with you. You wouldn't want anybody thinking you brought a club with you!

In the beginning, my favorite part of the Rainbow Heart was its ability to catch and hold my attention. Weak, I know, but it's how I've come to buy my toys. If I can't take my eyes off it, I get it! Once I finally had it in my hands, all the nubs are what kept me going. For most, there would be far too much texture since the nubs are high in number, but there are other options.

Luckily, you could use this toy for sensory play, for a good between-the-shoulders massage, and—I do believe I even read from another reviewer—as a back scratcher!

I don't want to say that most users are more than likely going to be at sensory overload with this toy and will not be able to handle it. But I do feel like a good number of them will run into that wall. For me, I had nothing but a whirlwind of pleasure, especially since the handle allows you to turn during thrusting, allowing for a bit of variety.

Pyrex glass is way easy to care for. It's nearly impossible to break. Even though I say that, I do strongly recommend storing it in a padded pouch. Why? Because you want a toy as wonderful as this to last as long as it possibly can!

Another great thing about glass is that you can use ANY kind of lubricant with it. However, you will want to be careful. Once lubed up, glass is extremely slippery and is hard to keep ahold of.

While you have a ton of options for cleaning it, I almost always recommend a 10% bleach solution, although one could use mild soap and water to clean it just as well. You probably could put this through the dishwasher as well, which also leaves the option of boiling it: While I don't recommend it, it can be done as long as you put the glass in the water to let it heat WITH the water.

While I've read that some people got theirs in a padded pouch, I didn't have such luck. Mine came in a red velvet drawstring bag with a silky interior. It keeps it away from other toys and will offer some protection while stored. However, if you plan on traveling with this one, definitely get a padded pouch. Pyrex glass may be extremely tough, but it is still glass.

While a lot of people are saying that this isn't a toy to use for G-spot stimulation, I have to wholeheartedly disagree. As long as you're careful, you can angle this toy just right and hit your G-spot. There are no words to describe it, especially if you're all about textured toys.
