"Pana-Tetra"is a Zinc oxide single crystal made of pure zinc grain,processed using a breakthrough method to provide oxidizing-heat-treatment under special atmospheric conditions. With its characteristic 3-dimensional configuration(tetrapod shape),"Pana-Tetra" offers not only the special advantages of single crystal but also provides remarkable effects of compound resin, that no other compound-filler can achieve.
