The Rainbow G is a textured glass dildo that is both pretty to look at and fun to use. Riddled with nubs, gifted with a slightly bulbous head, and designed with a vicious curve, the Rainbow G offers varied sensations that change with each thrust and twist. It can be used vaginally or anally, as the flat and slightly flared-out base of the toy gives you something to hold on to, and since it's made of safe and sturdy Pyrex glass, it is easily cleaned and sterilized. Overall, the Rainbow G is a versatile glass toy and most definitely will not disappoint.

The Rainbow G is made from Pyrex glass and manufactured by SSA Glass. It is nubbed along the shaft, and is very firm and rigid, with no give. The head and some parts of the shaft are smooth, so depending on how you twist the toy while inserted, you may feel the nubs constantly or you may not feel them at all.

Glass is nonporous and one of the safest materials for toys to be made of. It is hypo-allergenic, latex free and phthalates free. It is also waterproof and compatible with all types of lubricant. There's no odor at all, and being made of Pyrex glass (think kitchen cookware) means that it won't shatter into shards if it breaks; instead, it'll chip and fracture into chunks.

Before playing with the toy, you should always check it for nicks, chips, and cracks. It can be heated or cooled down for temperature play, but you shouldn't stick it in the oven or switch extreme temperatures too quickly. Also, when playing, be careful not to thrust too hard as glass has absolutely zero give and can cause bruising to your cervix.

The toy is a little smaller than I expected, but I think that is due to the "S" shape. The head of the Rainbow G bulbs out gently (less so than the Blue Swirl G), but the curve is much more sharp and defined. The nubs along the shaft are situated in an interesting pattern. Directly below the head and above the base there are two rows of nubs, red and blue respectively. Down either side of the shaft there is a single column of yellow nubs. This makes for varied stimulation regardless of how you're thrusting or twisting the toy.

The size is not intimidating at all; mine measured in with an overall length of 7-3/4" and a circumference of 4-3/4" at the widest part. For anyone new to glass, or curved toys, or textured toys, I'd say that this is a good one to start with as nothing about the toy is overly big or scary, but there are a lot of things going on with the toy at once. It might take a bit of trial and error to find the right hold for you.

The toy is travel friendly; just pop it in its padded black pouch and go.

The toy performed exactly as it should have, although the curve was a bit too much for my personal tastes. The nubs along the shaft are noticeable enough to add a teasing, almost tickling sensation along my labia, but not so prevalent as to take away from the other design aspects of the toy. The nubs along the base of it add a little to the grip if you're holding it just right. The wider base also helps with the handling of the toy. I wish it were a bit longer, or had a handle or something on the end, because the flat base isn't quite big enough for me to have a firm, confident grip on and sometimes the toy slips out of my grasp, even without using a lubricant.

The Rainbow is extremely low maintenance. Glass toys are extremely easy to clean and this one is no different; you can either wash it with soap and warm water, boil it, use a 10% bleach solution, toy cleaner, or throw it in the dishwasher on the top rack.

It comes with a padded black pouch for easy storage, but don't just go throwing it around as you may chip the glass. Don't put the toy through sudden, extreme temperature changes either as this will stress the glass and cause it to fracture. Always check the toy for nicks, chips and cracks and never use one that has them.

It's compatible with all types of lubricants.

The Rainbow G came in a padded black velvet pouch and was wrapped in bubble wrap, so the packaging was very discreet, as has been my experience with SSA Glass. The pouch makes a perfect storage space for the toy, and allows it to be travel friendly since it offers a little protection against being jostled around.

This toy was my introduction into the wonderful world of textured glass. The overall rigidity of the toy, the nubs that are interestingly placed, and the sharp curve meant that I had to do some experimenting to find a good hold and position for the toy to hit everything just right.
