The Utsumi 124 Carbon Comb is 8.5" long. Half the comb has closely spaced teeth, while the other half has widely spaced teeth. This makes it ideal for working with fine or thicker hair types. Carbon Comb are completely anti-static, so they do not tangle the hair. The teeth are incredibly smooth so they easily move through the hair. The Carbon combs are heat resistant, can be sterilised by boiling. (Utsumi was formerly known as BW Boyd). Made in Japan.
