Oster Master Flat Top Comb for the Oster 1-2-3 System. The Oster 1-2-3 system was developed to increase efficiency. To compliment the ""clipper over comb"" technique, Oster created the 1-2-3 flat combs. The Master Flat Top Comb is strong, yet flexible, virtually unbreakable, heat resistant, chemical resistant, friction resistant, static free, sterilizier compatible, long lasting, and flat not bulky.

The Master Flat Top Comb is designed for flattops, blending, tapering and clipper over comb techniques.
