The Nubone 210 is the Classic Plus Cutting Comb, 7.25 * 1.25. Oversized contemporary design combines detangling teeth with styling teeth. High heat resistance makes it ideal to use with popular hair straightening techniques like Brazilian keratin hair straightening, Japanese straightening and traditional flat ironing. While other combs are quick molded plastic, each NuBone comb is hand crafted from 100% organic resins. Every handle, tail, and tooth is hand sanded and polished to an exceptional finish. Developed to duplicate the weight, hardness, feel and performance of the original bone combs.
