This pair of beautifully made glass eggs has a fun swirl of color. They are perfectly smooth. For easier insertion into the vagina, you may want to use a dab of your favorite lube or rub your vulva/clit a little to get your juices flowing. You can use one or both at a time.

The instructions give a good recommendation of how often and how many Kegel exercises to perform (build up to a few times per day for a few minutes each time). The eggs add some extra resistance similar to lifting a heavier weight at the gym. It is not a good idea to perform Kegel exercises all the time throughout your day because it is possible to fatigue your pelvic floor musculature.

The instructions also provide guidance on how to know if you are activating the correct muscles. Another method which does not involve inserting a finger is to stand with your hands resting on a table, legs spread, turn/rotate your legs inward, then try to squeeze your butt/glute muscles. You should feel that a very different muscle is tightening.

Learning how to perform Kegel exercises properly can lead to improved orgasms and increased pleasure for your male partner.

The eggs are made out of glass and easy to clean. Glass is non-porous, meaning that it will not harbor bacteria and it can be sterilized. Since they are glass, use caution cleaning or transporting them so that you do not drop them and risk breaking or chipping them.

They come with a small black pouch which makes them easy to take along in your purse.

Unfortunately these little eggs do not have a string or tail to pull them out so it would not be a good idea to insert them into other orifices. Personally I haven't used other vaginal exercise devices but a method of removal would make these eggs much easier to remove. I'd also recommend wearing panties in case they fall out.
