"7"""" (17.8 cm), fine/coarse tooth area for a fine hair cutting technique, rounded, strong back, for 0.5 mm cut.Consists of particularly high-quality thermoplastic and therefore extremely flexible. Tooth tips have been neatly rounded by hand, as is otherwise only possible with rubber combs. The SILKline combs are polished, glide easily through the hair and are very scalp-friendly."
