[Negative Ion Technology] The negative ion curler releases negative ions to retain moisture in the air, moisturize hair, prevent tangles, and help restore curls to a healthy shine. [PTC Thermal Conductor] The foldable negative ion curler is made of Korean ceramic. The ceramic glaze heats up quickly, conducting heat five times faster, accelerating heating in 30 seconds for even heating and lasting up to 48 hours. [Anti-Scald, Anti-Static, Scalp Massage] The curler core heats to 200°C, while the comb heats to just 50°C. This optimal temperature prevents burns.
