A marking instrument having a plurality of removable writing nibs serially aligned so that an operator can remove a spent or fluid-affected writing nib and, thereby, access a fresh writing tip.

A hand held device presenting a first head and a second head that are movable axially between a position for use and a retracted position, and a single side button configured to bring the first head and the second head, independently of each other, from the retracted position to the position for use and vice versa, the side button cooperating with a first ratchet mechanism in order to cause the first head to pass from the retracted position to the position for use and vice versa, and with a second ratchet mechanism in order to cause the second head to pass from the retracted position to the position for use and vice versa.

A ballpoint pen is provided in which the width of the drawing line can be changed, wherein responsiveness can be improved when distinguishing between drawing thin lines and thick lines. A ballpoint pen 1 provided at the pen tip side with a first writing part having a writing ball 25, wherein the ballpoint pen 1 is characterized by being provided with a writing part at the pen tip side with which it is possible to write a thicker line than the line written with the first writing part, only the first writing part being used when the writing weight is 1 g and the writing angle is 90, and the second writing part being used when the writing weight is 200 g, and the writing angle is 40-90.

A refill for a writing tool includes an ink containing tube that is made from a resin material and formed in a straight cylindrical shape, and a writing tip that is attached to an end of the ink containing tube. A press-fit portion, formed at the end of the ink containing tube, has a thickness being made thickened toward an inner circumferential surface and has an opening hole penetrating in an axial direction at a central portion of the press-fit portion. The writing tip or a relay member supporting the writing tip is press-fitted and attached to the press-fit portion. The refill for a writing tool can ensure a necessary and sufficient amount of ink stored without expanding an outer diameter of the ink containing tube, and sufficiently secure mechanical strength of an end portion, and a writing tool using the same can be provided.

A multifunction writing instrument comprising a body extending along an axis and receiving at least two writing elements, each writing element comprising a writing tip and being movable between a protruded position in which the writing tip extends out of the body and a retracted position in which the writing tip is retracted within the body, and an actuating mechanism comprising a spinner configured to move one of the writing elements at a time, one after the other, from the retracted position to the protruded position, a ratchet receiving the spinner, and a single button configured to actuate the actuating mechanism.

Multifunction writing instrument comprising a body extending in an axial direction and housing at least two retractable writing elements and a ring portion movable in rotation. The ring portion having at least as many pairs of guide surfaces as retractable writing elements. The writing elements include buttons. Each button is configured to cooperate with a respective one of the pair of guide surfaces of the ring portion. Actuation of the button of a writing element facilitates movement of the writing element from the retracted position to the writing position and returns any of the other writing elements in the writing position to the retracted position, whereby at most, one writing element is in the writing position.

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.

Presented is a smart multi-color writing tool in the form of a pen having a color capture and replication capability, and is equipped with a novel ink dispensing, mixing, and delivery system. The multi color writing tool is configured to capture/scan any colors from variety of objects or images, store the captured colors from the objects or images within a local memory unit configured within the tool or transmit the same to a remotely located computing device, and make use of the captured colors for writing on, marking, or coloring objects, paper, and/or other suitable surfaces.
