The Dichroic Spiral, or Rainbow as I prefer, is a very pretty glass dildo by Phallix and my first from this company. One of the most stand out characteristics about it is the spiral that is wrapped around the whole length of the shaft. When in the light this portion sparkles and shines in different rainbow colors. This is one of those glass toys that you would definitely want to keep on display for everyone to look at. It even has a base that makes it perfect for standing up for your viewing pleasure (and safe for anal use). A great thing about the spiral is that it doesn't only appeal to the eyes, but it is also fun for other body parts because it is raised. It can be used vaginally, rubbed on the clitoris and labia, and also be used for anal play. Any glass collector needs to add this one (or one of the others that are similar) to their collection.

Rainbow came packaged in a clam shell type plastic container with a lilac silk pouch. This pouch is not padded and will simply work to keep the toy from getting scratches, but will not keep it from breaking should it be dropped. Although it does not offer much in protection, I still keep Rainbow in there and just make sure that it is in an area with some cushion. There is a little insert included about Phallix toys and about glass toys in regards to care.

I sing the praises of glass every time I review a glass toy, and I will continue to do so. Glass is an awesome material because it is body safe, easy to care for, and because it can be used for some fun temperature play. It can be used with water, silicone, or oil based lubricants. To clean it just use soap and water or a toy cleaner. Wipe it down with a 10% bleach solution or boil it to sanitize it. When I first received Rainbow it had been very hot and humid, so I was happy that I could have some cold fun by letting it sit in a bowl of ice water. These shivery sensations lasted a good amount of time and felt amazing! The raised swirl feels really good as it provides a cool massage for my genitals. However my body heat eventually warmed the toy up and caused some nice warm sensations as well. The only downside to glass is that it can break, but this one is made out of Pyrex which means that it wont shatter and will break into large chunks. Care should also be taken during thrusting to not hit and/or bruise your cervix or other internal tissues.

There are 2 different sizes that this one comes in: 1.5 inches in diameter and 1 inch. The one I chose is the 1 inch. This diameter refers to the shaft of the toy, as the head of mine is a little more than 1.25 inches in diameter. Another thing to note is that the 1 inch seems to refer to the diameter without taking into account the spirals, these add at least 1/8 of an inch to the shaft. I tend to go for larger toys, but this one feels bigger than I was expecting and I like that the size is not too intimidating for me to use for anal play. In regards to the length, it has about 6.5 inches insertable which is a little long but I can still insert most of it with no problems.

The spiral that wraps around the entire shaft is thicker than most spirals I have experienced on other toys. In my opinion, this makes the texture less likely to be irritating during use and it also gives a mini "bump" kind of sensation as it is thrusted. I really like this and I think it would work better for those who might be selective about the texture they try on toys. The head is completely smooth and is a bit larger than the shaft, but nothing that would be uncomfortable. In fact I would have liked it if it were bigger than what it is but it still works for me. Once inserted the spirals can stimulate the entrance of my vagina and my g-spot. With such a firm material I can apply direct pressure to my g-spot which makes me very happy. Although the shaft does not have an intense curve, due to my anatomy, I can get a little bit of clitoral stimulation at the same time when I use this.

As I mentioned, I really enjoy this one for vaginal use because I can angle it to stroke my g-spot and provide firm pressure and I am also able to get some clitoral stimulation at the same time. Due to the fact that this one is not overly large, I was able to give it a try for anal use. At first I was afraid that the texture might make it feel a little too big for me, but I was pleasantly surprised. It was very pleasurable to insert this and use slow in and out motions. This was one of the longest toys that I have used for anal play and I really like being able to insert a good amount of it and feel the spirals inside of me.

Something else that I wanted to mention is that I was happy that my Dichroic Spiral looks like the one in the pictures and the one that is shown in the actual size picture. I wasn't sure if this was going to be the case because there is variation in each individual glass piece. I was hoping mine looked like the one that another contributor showed in the video (due to the large head that was shown), but I am still happy with what I got.

The Dichroic Spiral is one of the prettiest toys in my collection and I still enjoy using it. It is nice when I don't want a ton of texture and is one of my favorites to use for temperature play because the spirals feel so good cold when the toy is being thrusted. If you can afford this one I think you will be very happy if you decide to give it a try.
