The Utsumi Carbon Cutting Comb is 10" long with 3/4" length teeth. Half the comb has tightly spaced teeth, while the other half has widely spaced teeth. The 295 Carbon Comb is completely anti-static, so it does not tangle the hair. Is heat resistant and can be sterilised by boiling. Teeth are incredibly smooth so they glide through the hair. Made in Japan.
