The new fiber “NEORON®” was invented exclusively for NEFFUL. Both NEFFUL and TEIKEN have put forth full devotion towards the innovation of NEORON®’s research and development. All our efforts have been focused on implementing NEORON® into production. The new technology and research invested has suggested that NEORON® creates better material blends for better products! NEORON® is made from most of the same materials as Teviron and retains all of its features. Neoron®’s extensive line of products employs negative ion technology just like our old line Teviron! Neoron® supplies you with negative ions at all times, delivering health benefits like never before!
