What it is: A set of two 1.5-inch hot rollers and clips to supplement the T3 Voluminous Hot Rollers Set.What it does: Each roller contains a high-performance ceramic PTC heater (commonly used in digital flat irons) with heat-sink core, which heats up in two to three minutes and maintains precise temperature control for perfect results. A high-grade aluminum core also provides superior heat retention comparable to a wax-core roller, but with quicker heat-up time. Infused with T3 Tourmaline technology, the rollers are also designed with flocking, which helps to grip hair while imparting natural shine to hair. The included spring-loaded butterfly clips are also specially designed to keep the large diameter rollers in place without leaving any creases in the hair.This set contains:- 2 x 1.5" Voluminous Hot Rollers- 2 x spring-loaded butterfly clips
