The application relates to a porous color linker comprising a tip portion configured to deposit indicia on a writing surface; a mixing portion configured to combine a plurality of inks; and a base portion having a first receiving portion configured to receive a tip of a first ink discharge device and a second receiving portion configured to receive a tip of a second ink discharge device.

A double-head marker pen includes a first penholder, a second penholder and a connecting tube; one end of the first penholder is formed with a first pen head, and one end of the second penholder is formed with a second pen head; and an end of the first penholder away from the first pen head is detachably connected with an end of the second penholder away from the second pen head by the connecting tube.

A handheld implement, configured for example as a writing-instrument, having a shaft that has at least two shaft parts which are releasably connectable together via a plug-in coupling, which have a coupling unit at each front end of the shaft parts. Each coupling unit has a slide that is held immovably in a guide hole open on a face side in the associated shaft part and protrudes beyond the guide hole with a slide portion, the free end of the slide portion is formed as a latching fork that has a latching opening between two fork arms, that the slide portion bears a latching protrusion on its inner side behind the latching fork in the sliding direction, the coupling unit has a guide sleeve that encloses the slide and is guided movably in the guide hole counter to the restoring force of a spring- or rubber-elastic restoring element, and when the front ends, having the coupling units, of two shaft parts are pressed together, the latching fork of one coupling unit is latchable on the latching protrusion of the other coupling unit with at least one of the guide sleeves being pushed back.

A feeding pencil includes a pipe member, a leading tube, a tubular main body, a movable body, and a holding member. The pipe member is disposed inside the leading tube and loads a drawing material. The movable body extends in an axial direction includes a male screw formed across an entire outer periphery thereof in the axial direction. The holding member holds the movable body. The pipe member includes a female screw on an inner surface thereof. The female screw screws with the male screw. A relative rotation between the leading tube and the main body relatively rotates the pipe member and the holding member and acts a screwing action between the male screw and the female screw. The screwing action moves the movable body forward to extrude the drawing material from the pipe member.

Provided herewith is a marker that has multiple colors and retracts and seals the ink reservoirs. Also provided is a method of selecting a color.

An electronic pen has increased strength, especially a pen tip portion that is not bent or broken even if the electronic pen is slimmed down. A core unit includes a ferrite core on which a coil is wound and a core rod. The core rod is fixed from a first end of the ferrite core to a second end of the ferrite core at a position including a center axis of the ferrite core and projects at an end thereof from the first end of the ferrite core. The ferrite core includes a first coil non-winding portion on which the coil is not wound provided on the pen tip side of the ferrite core. In operation, the end of the core rod and part of the first coil non-winding portion of the ferrite core project from an opening of a housing of the electronic pen.
