Energy Balls or Dodecahedrons are believed to give the person wearing them more energy. A Dodecahedron is a three-dimensional shape having twelve plane faces. Our Energy Balls have twelve sides and each sides forms the shape of a star. We were told by a scientist that there is something in space that is shaped like a dodecahedron that has particles inside that are constantly moving causing lots of energy thus the name “Energy Ball”.
