Cosmetic Brushes: The term brush refers to devices with bristles, wire or other filaments, used for cleaning, grooming hair, make-up, making paintings, deburring and other kinds of surface finishing, and for many other purposes.

Configurations include twisted-in wire (for example the brushes used to clean baby feeding bottles), cylinders, and disks (with bristles spread in one face or radially).

A common way of setting the bristle in the brush is the staple or anchor set brush, in which the filament is forced with a staple by the middle into a hole with a special driver and held there by the pressure against the walls of the hole and the portions of the staple nailed to the bottom of the hole. The staple can be replaced with a kind of anchor, which is a piece of rectangular profile wire that, instead of nailing itself to the bottom of hole, is anchored to the wall of the hole, like in most toothbrushes. Another way to attach the bristles to the surface can be found in the fused brush, in which instead of being inserted into a hole, a plastic fiber is welded to another plastic surface, giving the additional advantage of optionally using different diameters of tufts in the same brush, and a considerably thinner surface (sometimes the bristles can be set this way to the outer surface of a plastic bottle).
