Compositions which can be applied to body hairs or head hair, comprising an aqueous suspension of magnetic latex microspheres and of colloidal nanoparticles of magnetic pigment. The method comprises the steps of: forming a diaphragm pack comprising a flat stack of composite plies between two diaphragms, wherein each ply of the flat stack is made up of a plurality of composite tiles. the average Wa of the width of the crown plate support existing in the foreside one-quarter zone of the top opening, the average Wc of the width of the crown plate support existing in the backside one-quarter zone of the top opening, and the average Wb of the width of the crown plate support existing in the mid two-quarter zone of the top opening satisfy Wa>Wb, and Wc>Wb. When the counter element reaches a threshold value, which is indicative of a large maximum number of occurrences of the events, the indicator element goes from a first state to a second state. The ink cartridge also includes a rib member extending from an exterior surface of the second wall.
