InStyler | Hair | Topsyler By Instyler Clamshell Curlers 。TOPSTYLER reinvents hair styling, allowing you to easily create beachy waves, curls and add amazing volume and body. The secret to TOPSTYLER is in the breakthrough design of the patented ceramic tourmaline C-Shells which surround the hair and infuse gentle, even heat long the entire length of the hair. Unlike curling irons which release the hair while still hot, TOPSTYLER\'s Ceramic Shells hold the curl in place until the hair is completely cool-set. TOPSTYLER\'s 100% Solid Ceramic Shells surround the entire curl transforming the curl without frying the hair.
