A nib for a refillable free ink writing felt pen includes a body and a dry ink tank including dry ink, the dry ink tank being delimited by the body of the nib and a dry ink tank wall including a breakable portion.

Provided is a writing implement that maximizes the effective area of a viewer portion allowing visual recognition in the writing direction and that facilitates writing at a high level, at the same time. This writing implement is a writing implement A, including for example, a pen tip 20 that feeds ink from a writing implement body 10 and has a viewer portion 33 allowing visual recognition in the writing direction. The pen tip 20 is comprised of, at least, a writing part 25 and a retainer 30 having the viewer portion 33, an ink feeder portion 26 for feeding the ink from the writing implement body 10 to the writing part 25. The minimum width X of the viewer portion 33 is 3.7 mm or greater and a length Y of the viewer portion 33 is 7.4 mm or greater. The ink feeder portion 26 is arranged on one side of the viewer portion 33. Specifically, the ink feeder portion 26 is preferably adapted to be positioned on a near side during writing (on such a side that the pen tip 20 is located on an obtuse angle side of the ink feeder portion 26).

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.

Provided are processes of placing an image on an object that includes optionally filling a hand held nib-based marker with a child and environmentally friendly aqueous based heat transfer disperse dye ink composition, and imaging an intermediate substrate with the marker. A process optionally further includes optionally drying the image, optionally heating the intermediate substrate, optionally placing the inked intermediate substrate in contact with a dye receptive surface of a receptive object, and optionally transferring the image to the receptive object by application of sufficient heat and pressure.

A liquid ink instrument, including: a pen body, a writing element mounted on the head of the pen body, an ink absorber mounted at the rear end of the writing element; a fiber ink feeder mounted in the body penetrates the ink absorbing body, the front end in contact with the writing element, the rear end communicated with the ink cartridge; at least one air-liquid balancer in the axial direction, the air-liquid balancer installed between the recited fiber ink feeder and the body; having one or more air-liquid exchange grooves penetrating through the outer circumferential surface; having an overflow groove on a radial surface of the air-liquid balancer, one end contacted to fiber ink feeder, and the other end communicating with air-liquid exchange groove; a gas-free fit or an interference fit adopted between the outer circumferential surface of the fiber ink feeder and the inner wall of the air-liquid balancer.

A marking implement assembly for placing a mark on tissue, including a marker body including a marking implement extending from the marker body, a cap configured to fit to an end of the marker body so as to cover the marking implement, the cap including a housing providing an ink reservoir, where when fitted to the marker body at least a part of the marking implement is in fluid contact with the ink reservoir, the cap fitting onto the marker body in fluid tight manner.

Lines can be freely varied in thickness, and lines with characteristics such as stops, flicks, and sweeping strokes can be written easily, even with a felt-tip pen, marker pen, or the like. Moreover, a pen-tip does not readily become damaged or worn. A writing implement includes a shaft, an ink supply core such as that of a felt-tip pen or a marker pen, and a core surrounding member that covers the ink supply core. The writing implement is formed capable of contacting a tip of the ink supply core and a tip of the core surrounding member against a writing surface at the same time by using a joint capable of changing a relative positional relationship between the ink supply core and the core surrounding member.
