The Jade Egg and the Rose Quartz Egg, which the website is calling Yoni eggs, apparently "harness the power of energy work, crystal healing, and a Kegel-like physical practice."
You're supposed to start with the Jade Egg and move on to the Rose Quartz Egg when your vagina is ready to take the next step. The Jade yoni egg's "power to cleanse and make them ideal for detox"
They say users of the egg(s) say it increases their fundamental life force, hormone balance and more.
UPDATE -- The eggs have sold out!
