The Rainbow Mega Nubby is 7 1/4 inches in length and 1 1/8 inches in diameter. The shaft is completely straight, with no give due to it being made out of glass. Even though this toy is on the small size,diameter wise, the fact that it is made out of glass and highly textured makes it feel a bit larger, so I didn't mind too much. It came in a clamshell plastic package with a pink padded storage bag, which is great for protecting it from drops or other accidents. Since this toy is made of glass, it can be used with any lube that you desire and comes with a sample of Wet brand silicone lube! The Mega Nubby can be cooled down or warmed up using a bowl of ice water or warm water. Be careful not to use water that is too hot because this material heats up very quickly.

Once I took it out of the package I realized how much fun this toy looked and felt. I love all of the colorful nubs because I have found that most of my toys are one solid color (usually pink). This was something fun to add to my growing collection. The glass nubs felt SO good when I rubbed them across the palm of my hand and I could not wait to try it out. I enjoy texture; but, due to the vast amount of it on this toy, I sometimes use a tiny drop of lube to make insertion easier. This also may be necessary for those who are new to texture on very firm toys.

When it comes to cleaning, because this toy is made of glass, I usually wash it with warm water and anti-bacterial soap or I use toy cleaner. When cleaning it is important to pay attention to anything that may get stuck around the nubs, so it is usually easier to clean when I can clean under running water.To sanitize, a 10% bleach solution can also be used.

I use this toy both internally, as the nubs provide amazing stimulation to the entrance of the vagina, as well as clitorally. One of my favorite ways to use this is to stick it in cold water for a while and use it for external stimulation. It feels great this way! For internal use, I enjoy thrusting with it, but sometimes it is nice to slowly spin it around inside of me and feel the nubs swirling around!

In addition to genital stimulation, the Rainbow Mega Nubby also feels great when rubbed over other parts of the body, such as nipples.

I don't like the Rainbow mega nubby as much as I used to. I have had this for about a year and at first I used it a lot, but then I stopped liking the straight shape of it in combination with the texture. I have other textured toys that have more curve that I enjoy a lot more. I wont say that I do not like this at all, but I would give it 2.5 stars instead of the 4 stars I gave it before. It kind of sits in the bottom of one of my drawers and is rarely used.
