Abstract
Abstract A make-up brush comprises an injection moulded frusto-conical support having integral bristles with enlarged ends. The bristles in certain rows have hooked ends directed towards an extension of the support (to engage a handle) and the bristles in other rows have hooked ends directed away from the extension. The brush support is moulded using a segmented cavity die which has recesses defining the integral bristles.
