The YS-239 is the very first comb that attaches to you so you can focus on cutting. The curved base is designed to sit on the ridge between your fingers, so your fingers simply fall into place where it’s comfortable to add support. The comb teeth are 2 mm thick (1 mm thinner than standard YS PARK cutting combs and 1 mm thicker than styling combs), making it an ideal intermediate size for creating fades as well as controlling longer hair sections. The YS 239 is stiffer than its counterpart, the YS 209, making it easier to control longer hair sections while still maintaining enough flexibility to work efficiently with scissors over comb.
