All Gem Feet attach to the bottom of the Otto Tune Tuning forks in 128, 136.1, or 64 htz (25mm recommend for 64 htz). They enhance the vibration and also administer the healing traits that are associated with the mineral or crystal. These feet are hand made in Germany.
The 6mm is ideal for auricular therapy, which is working the meridians on the ears.
The 15mm sizing is great for acupuncture, on bones, and acupressure points. Allows a direct stimulation to the focused meridians resulting in a spike of Nitric Oxide.
You can easily apply essential oils as well to the tips of these forks to also amplify the healing qualities of the essential oils
