The 1.75†diameter T3 Voluminous Hot Rollers create voluminous soft waves for longer hair types and body and volume with no curl for shorter hair lengths. Also includes 2 spring-loaded butterfly clips to hold rollers securely in place during styling. T3 has reinvented hot roller technology to create contemporary looks with voluptuous waves or curls and incredible shine. With advanced technology in each roller, every strand of hair will have volume, shape, movement, and shine. The Voluminous Hot Rollers have been designed with proprietary Tourmaline technology and a ceramic core, which emits maximum ionic, infrared heat to safely penetrate the hair shaft, effectively styling the hair while sealing the hair cuticle against frizz. The velvet flocking along the roller surface enhances the effects of Tourmaline, imparting natural shine to hair during the styling process.
