A writing utensil puzzle kit for amusement and advertising purposes. The writing utensil puzzle kit includes a shaft, a writing member affixed to the shaft, a front housing piece securable to the writing member, a rear housing piece having a front end and rear end, wherein the rear end is securable to an end cap. A plurality of central housing pieces having a central channel that can receive the shaft, wherein each of the central housing pieces are securable to one another in a particular order via a threaded protrusion disposed on a front end thereof that can removably secure to a recessed channel disposed on a back end of an adjacent central housing piece. A gripping member is mountable to the housing piece. In an additional embodiment, the gripping member includes a plurality of interlocking gripping members with indicia thereon for indicating the particular order of connection thereof.

Angled pens are provided. A pen includes: a shank; an ink tube inside the shank; a first tip member connected to a distal end of the shank; a second tip member connected to a distal end of the first tip member; and a bent tubular member including a proximal end section, a middle section, and a distal end section. An axis of the middle section is arranged at a first angle relative to a central axis of the shank. The axis of the middle section is arranged at a second angle relative to an axis of the distal end section, the second angle being in a range of 45 to 90. The axis of the distal end section is arranged at a third angle relative to the central axis of the shank.

A writing instrument includes a first barrel and a second barrel that are able to rotate relative to each other about the axial direction, and presenting a first distal end and a second distal end, a writing tip being arranged at the first distal end while a pad for a capacitive screen is arranged at the second distal end, the writing tip and/or the pad for a capacitive screen being retractable by causing the first barrel to rotate relative to the second barrel, and where a barrel among the first barrel and the second barrel includes a tongue extending in the circumferential direction, the tongue being configured to establish electrical contact with the other barrel among the first barrel and the second barrel.

The use of an element for a writing, drawing, marking, and/or painting device, or cosmetic device, or input device for touch-sensitive surfaces, wherein the at least one element is a 3D-printed element. The at least one element has at least one main body and at least one structure. The at least one main body consists of a first material component. The at least one structure is provided as a visually detectable structure and/or at least one structure formed as a haptic zone. The at least one visually detectable structure and/or at least one structure formed as a haptic zone is a raised structure which projects from the surface, or the at least one visually detectable structure and/or at least one structure formed as a haptic zone is a decorated zone of the surface.

In one embodiment, a writing instrument refill includes a first portion having flexibility, and a second portion having a cross-sectional area larger than a cross-sectional area of the first portion, wherein the center of figure of the cross section of the first portion is offset from the center of the figure of the cross section of the second portion, the first portion and the second portion are formed integrally, and a part of the first portion has an outer diameter smaller than an outer diameter of the other part of the first portion.

A compact ballpoint pen in which a bar of a push button is split into left and right bars and thus an ink cartridge can be inserted into a space between the split bars. Thus, the length of a ballpoint pen is reduced.

A pen system comprising a cover member joined to an adapter having an anterior end of an ink cartridge disposed therein is disclosed. A pen housing covers the ink cartridge and is sealed via a plug. In one embodiment, a slit divides a surface of the adapter to allow a collapse of the adapter, thus narrowing a height of the adapter, to allow insertion of the adapter into the cover member. A first and second annular groove are disposed at a center of the adapter, where each annular groove interfaces with a cover member annular ridge to define an open and closed position of the pen. In an alternate embodiment, an annular washer having an annular ridge is disposed in the cover member, in place of the cover member annular ridge, to interface with the first and second annular groove thus defining the open and closed positions of the pen.

A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.

A sound confining ball-point-pen 100 includes a body, which is in vacuum state, having a first opening at one end and a second opening at another end, a knocking mechanism placed in the body at a location close to the second opening, a core of the sound confining ball-point-pen 100 stored in the body, the core being moved by the knocking mechanism, a protective cap, which is fixed to the body, for covering the second opening, whereby the protective cap prevents air for entering into the body from the knocking mechanism, and a sealing means placed in the body at the location close to the first opening for sealing the first opening when the core of is set back into the body.

A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.
