This is the Duotone orgasm balls set by Cal Exotics. It has two balls connected together by nylon string, and the knots are on the inside of them. It's a beautiful pink and white marble pattern, with a seam that can't be felt. When you shake them you can feel some type of weights in them. It's meant for vaginal use and isn't considered to be safe for anal use because it has no base, but I personally enjoy using it anally as it gives me a wonderful full feeling when inserted back there.

It's a smooth plastic that's latex and phthalates free, and Hypo-allergenic just in case someone's allergic to materials. There was a light smell when the packaging was first opened, which is to be expected because of the newness of it, but the smell dissipated shortly after the initial opening.

I got mine in pink and white (I just love the marble-type patterns). Its total length is 8-1/2 inches, with an insertable length of 6 inches, and a circumference of 4-1/8 inches. Both balls have a seam in the middle of them, but you can't feel them which I think is great. Its total weight is only .2 of a pound. I do wish that it was bigger; maybe 5 to 6 inches around would simply be mind blowing for me. These would be great for someone who doesn't like the more robust objects. Basically, for beginners and intermediates.

I worked and slept with them in vaginally for two days, and there was no motion from the weights inside. They felt good going in, but shortly after I soon forgot that they were still in. The only reason that I knew that they were still in was I felt the string and some light pressure on my pelvic bone. If not for that I'd still have them in.

Since it's made of plastic you can clean it with antibacterial soap and hot water, or wipe it off with rubbing alcohol, but it won't be totally clean because of the nylon string. You can cut the strings and just use the balls, but the holes left by the string will allow stuff inside the balls and it'd be totally useless (YUCK). It can be used with all 3 lubricant types: water, oil, and silicone based. If you share, it might be difficult to cover them with a condom, so it's best not to.

It came in the not-so-discreet bubble wrap, and the paper behind them only shows the girl's back. It's reusable for storing the balls back in and stashing the item in a duffel bag.

I like them, I really do, but I couldn't feel them once they were inserted. I'm thinking that they need something else for the balls to clank together and cause the sensation that they're supposed give off.

I have different types of these in different sizes, but this one I had to get because of its awesome color. In order to be able to do the review some justice I popped these in while getting ready for work yesterday, slept in them, and took them out this morning.
