The chromotherapy torch standard color discs are designed as a replacement to the older more delicate thin plastic filters which were provided previously in all older versions of the chromotherapy torch. They are made out of a very hard durable Perspex plastic, with the colors being delicately fabricated for correct color wavelength alignment. You will no longer have to suffer problems with the older style discs coming apart, or getting stuck in your crystal tip! The new style of discs fit in all older style chromotherapy torches which were previously available through Natures Energies.
Each of the discs measures 17mm in diameter and are approx 3mm thick.
