Copper is a soft metal with very high thermal and electrical conductivity. My favorite thing I have read about copper is that it carries the receptive energies of the wise Grandmother Earth, teaching us to walk in balance with nature. Thought to help one access and amplify their own energy both physically and energetically, and said to help balance the meridians.
These little copper spheres were mined in the USA. They are the perfect size to hold during meditation or cary on your person throughout the day. They are tiny but super weighted and grounding. Weighing about 4.4oz each and about 1.5 inches in diameter.
