The Utsumi, No 3 Ultem Comb is approx 6.5" long. It is designed with 33 evenly spaced teeth. It is good for clipper over comb, blending, trimming and flat tops. The No 3 Comb is made from ULTEM which is a high-strength plastic. It is more flexible than carbon and is static-free, so it does not tangle the hair. It is also heat resistant, so can be sterilised with hot water / steam. Teeth are incredibly smooth so they glide through the hair. (Utsumi was formerly known as BW Boyd). Made in Japan.
