The device comprises (a) a unitary integrally moulded elongate shaft forming an elongate handle having a proximal end, and a distal end of circular cross-section; and (b) a head comprising a body portion encircling the distal end of the shaft, and flexible filaments of non-absorbent material and of uniform diameter extending transversely from said body portion. The body portion and the flexible filaments are formed as an integral one-piece moulding that is fused to the distal end of the shaft. The rows of flexible filaments are distributed around the head, and each of the flexible filaments is of non-absorbent material and of uniform diameter, extending transversely relative to the integral one-piece moulding. |
