A brush for the application of nail varnish, or a similar product, includes a tuft obtained from a bundle of bristles which are substantially parallel and folded in two halfway along their length. The bristles are fixed at the folded part in a housing opening at the end of the rod. The bristles have cross-sections bounded by a circle of constant diameter and are chosen from at least two groups. The bristles of one group are arranged so as to exhibit a different mechanical behavior in flexure to that of the bristles of the other group so that these groups give a brush tuft which is open to the air and spread out, with relatively large spaces between bristles to promote good capillary action for varnishes whose viscosity may vary over a wide range.
