The Luna beads are used as a kegel exerciser for females. The basic understanding I have of how these work is that a rubber ball is placed inside the hard outer shell and placed into the vagina. As you move around, the rubber ball moves, but the outer stays in place inside the vagina. The movement from within the outer ball causes the muscles in the vagina to contract and strengthen over time.

I've heard this is used to improve both male and female sexual experience. In theory, stronger vaginal muscles should allow for an easier orgasm for the female, and it should feel tighter (which usually equates to "better") for the male partner.

This product also claims to cause "erotic sensations." Although I would not agree to that claim in my personal use of these, another female may find them stimulating in this manner.

The beads, or I refer to them as balls, are made of a hard plastic. They are smooth and non-porous, which makes for easy insertion. The girdle that can be used to hold two of the balls at once is made of silicone and is also smooth and easy to insert.

These balls were larger than I expected, but I found that to be a positive factor since even these may tend to slide out of some females at first.

Above, two of the balls are pictured without the girdle. One has a cord attached to it for retrieval.
Below, the balls are pictured in the girdle. In all honesty, I just picked the two first balls I had in front of me for the photo. I need to note that when using the girdle, however, you must always include one with a retrieval cord in order to get them out of your vagina easily.

NOTE: At this point and time, I am going to share my experiences as a new user of these. I will be writing a follow up once I reach the highest aspect of this system.

In this system, you get four balls. Two are pink, and two are blue. The color difference is to distinguish between the two weights. The pink are 1-ounce balls, and the blue are 1.3 ounces each. You begin slowly, especially if you are new to kegel exercises. Begin with the pink ball, which has the retrieval cord. If you require lube, you can rub a small amount on the outside of the ball. I caution you in lubing this, though, as the balls tend to slip out on their own if you are new to this. Insert the ball into your vagina so that the cord is on the outside. Insertion is much like a tampon, for those who are wondering.

As you walk around, the inner ball moves and causes your muscles to contract and strengthen over time. Gradually work your way up in weight: single pink ball, single blue ball, two pink balls, one pink and one blue ball, and finally two blue balls.

The manual that comes with this states that it make take several weeks for any notice of improvement in kegel muscles, but you should notice the balls staying in place easier as you go up in weight.

As for cleaning these balls, I would wash them in warm water and a mild soap or use a toy wipe. The material of them makes for easy cleaning, which is nice! Be sure to remove the balls from the silicone girdle when cleaning. While the girdle does grip the balls tightly, it is possible for bacteria to get between the silicone and the plastic.

I store these in the box that they came in or the satin pouch that is included. While I am on one set, I keep the next step up in the pouch on me, keeping the rest in the box. The pouch is good to keep on hand if you want to change the balls while you're out or if you need to remove them for any reason.

These balls were packaged in a black box with the signature LELO logo. This box was within another white box, which has a photo of the system on it. Included in this are: two pink 1-ounce balls (one with a retrieval cord), two blue 1.3-ounce balls (one with a retrieval cord), the silicone girdle, a small packet of lube, a black satin carrying pouch, an instruction manual, and a warranty.

I just want to note that when you first use these, you will notice them. It may feel uncomfortable at first to wear, but it does get easier. After a little bit, you don't even notice them as you walk around. Just give it a little time if they are uncomfortable, especially when sitting on a solid surface. Also, remember to take them out before sexual activity.

NOTE: Keep in mind that this is not an anal toy. Even if the ball has a retrieval cord, it should never be used anally. This is dangerous and could involve an awkward trip to the ER if you ignore this warning.
