The crystal sphere set consists of all four crystal spheres. These are crystal spheres attached to color rods (crimson, light green, light turqoise and rose) which can be inserted in the Perlux P117. For particular colorpuncture therapies, these spheres produce “lightening fast and long lasting reactions.”  See “additional resources” on this website for a brochure with instructions for crystal sphere therapies. Cost is $480.00 plus shipping.
