Embodiments of the invention are directed to a multi-component nib structure and marking device for selectively generating primary marks and a secondary marks for lettering and shading. The marking device includes a multi-component nib structure, an ink source. The multi-component nib structure generally includes a first nib component, a second nib component, and optionally, a transfer component between the first nib component and the second nib component. In other aspects, the multi-component nib structure may allow lettering with different tones creating, for example, an ombre effect.

An electronic board includes: a sensor sheet including X parallel electrode wires and Y parallel electrode wires, and a chassis to which the sensor sheet is attached. A sensor substrate is connected to a lower end of the sensor sheet. A sensor substrate is connected to a right end of the sensor sheet. The sensor substrate is disposed on a back surface of the chassis with a portion close to the lower end of the sensor sheet being bent to cover a lower end of the chassis.

An aqueous writing, marking and/or drawing liquid is configured for capillary systems, more particularly for applicator implements having a capillary system. The liquid has a viscosity of less than 50 mPas, more particularly less than 20 mPas (Brookfield, 20 C., cone-plate CPE-40). The liquid contains a wetting agent, graphite having a carbon content of between 95 and 99.9 wt %, an ash content of between 0.1 and 5 wt %, and a particle size 20 m at D90, and at least one release agent, more particularly in a concentration of 2 to 15 wt %. The release agent contains barium sulfate and/or an aqueous, highly mobile, nonsedimenting colloidal dispersion of nanoparticulate silicon dioxide particles.

A discharge head for a liquid dispenser for discharging cosmetic products which has a base to be secured to a liquid storage. The base has a coupling device in the form of a thread or a latching coupling device, for coupling to the liquid storage. The discharge head has a sponge carrier with a sponge receptacle in which a sponge is arranged. The sponge carrier is movable in a translationally guided manner with respect to the base and has a hollow connector inside which a liquid channel is provided that connects the liquid storage to the sponge receptacle. This liquid channel is provided with an outlet valve, which is opened by moving the sponge carrier in the direction of the base, such that liquid can flow freely out of the liquid storage into the sponge receptacle.
