A dry erase ink for a writing instrument. The dry erase ink includes, as the main organic solvent, a solvent selected from the group consisting of n-propyl acetate, isopropyl acetate, or mixtures thereof.

A pen has an ink reservoir configured to store an ink containing decorative particles and a pen tip configured to apply the ink to an ink coating target. The pen tip includes a proximal end to which the ink is supplied from the ink reservoir, a distal end opposite to the proximal end and configured to contact the ink coating target, and a groove opening on the outer circumferential surface of the pen tip and extending from the proximal end to the distal end.

A multi-posture bedside writing pen includes a pen shell, a pen tip holder, a fiber rod and a fiber ink storage tube. The fiber ink storage tube is connected with the pen shell and located in the pen shell. The pen tip holder is connected with one end of the pen shell. The pen tip holder is axially provided with a through hole. The fiber rod is inserted into the through hole, one end of the fiber rod is exposed outside the pen tip holder, and an other end of the fiber rod is inserted into the fiber ink storage tube. A first gap is provided between the pen tip holder and the fiber ink storage tube.

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 marking pen, comprising: a shaft cylinder; a porous pen core accommodated in the shaft cylinder, and configured to project from, and retract into, an opening part provided at a tip end of the shaft cylinder; an inner cotton accommodated in the shaft cylinder, and filled with an aqueous ink composition to be fed to the pen core, the aqueous ink composition including a water soluble organic solvent in an amount of from 20 mass % to 60 mass %; and a delivery mechanism configured to cause a tip end of the pen core to project from, and retract into, the opening part.

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.

To provide a writing instrument capable of further improving durability of a writing nib without impairing writing performance even when writing is performed with a heavy writing load. A writing instrument A having a writing part formed of at least a writing nib 30 made of a porous body and a retainer 40 made of a hard material, in which the protrusion amount of the distal end of the writing nib 30 from the retainer 40 is 0.65 mm or more and 1.05 mm or less and/or 40% or more and 65% or less of the thickness of the writing nib 30.

Provided is an assembly for a nail pen comprising: a) a nib made from a material that is configured to allow for movement of varnish from inside of the nail pen to the nib, and from the nib to a nail; b) a guide made from a material that is non-absorbent to the varnish, the guide extending below a surface of the nib that is configured to apply varnish to the nail; wherein a user applies a strip of the varnish to a distal portion of the nail by holding the guide against an edge of the nail and moving the nail pen along the distal portion of the nail so that the surface of the nib holding the varnish contacts the distal portion of the nail to apply varnish to the nail.

A writing tool has a pen tube, a capillary unit, and a dispensing unit. The capillary unit is mounted in the pen tube, and is connected to a nib. The dispensing unit is mounted in the pen tube, and has a communicating tube and a pressing segment connected to the communicating tube. The pressing segment has at least one connecting arm connected to the communicating tube. A dispensing interval is formed between the communicating tube and a periphery of the pressing segment. The communicating tube contacts the capillary unit to make the capillary unit form different compression densities via the pressing segment and the dispensing interval, thus facilitating dispensing ink downward easily through the dispensing interval and providing a better occlusion effect to further avoid ink leakage.

A biodegradable marker pen including a barrel, a cap, and an ink reservoir. The barrel has a hollow cylindrical structure, the ink reservoir is placed in the barrel, and the cap is detachably coupled with the barrel hermetically. The barrel, the cap, and the ink reservoir comprise 2 to 10 mass percentage of a biodegradable masterbatch respectively.
