Why obsidian gemstone?
Obsidian is a protective stone that shields against negativity, and absorbs harmful energies from the environment. This stone is believed to reduce the pain of arthritis, help joint problems, ease cramp, and aid digestion.

Safe, easy to clean, and crystal healing:
1) Safe: obsidian is a natural crystal. The balls are hand crafted without any chemical treatment, not even waxing. 100% natural and genuine.
2) Easy to clean: Kegel balls with string on the market are difficult to clean because of the porous string used, which is always a safety and hygiene concern. This set of kegel balls comes with one box of unwaxed & unflavored dental floss for use as the disposable removal string. When you do not need the removal string after your love muscles are trained stronger, you can wear the balls without the string. Safe, easy to clean and easy to remove.
3) Healing: Obsidian is excellent to assist you to release disharmony, resentment, fear and anger that have built up in daily life and work.
