A bristle support (14) is at the distal end of each of the first and second elongated necks. A plurality of bristles (15) extends from each of the first and second bristle supports, arranged substantially parallel to one another. The elongated handle and the first and second elongated neck are formed of a material having a predetermined flexibility, resilience and bending resistance. The bristles have a predetermined stiffness which is set according to a predetermined relation with respect to the predetermined flexibility, resilience and bending resistance. A furtherembodiment includes a resilient thumb contact (16) inserted in a cavity (16C) formed in the elongated handle, protruding from the handle at a thumb contact location.
