A mechanical pencil has: a shaft tube; a ferrule unit supported by the shaft tube; a lead holding unit having a chuck configured to relatively move with respect to the ferrule unit to eject lead held by the same; and an indication body provided movably in an axial direction. The indication body delimits from rearward a lead storage space formed rearward the chuck in the shaft tube. The indication body located at least at a predetermined position is viewable from outside the shaft tube. A length along the axial direction between a rear end of the lead storage space and a front end of the ferrule unit, in a state where the indication body has moved most rearward along the axial direction, is equal to or more than twice a length of spare lead to be stored in the lead storage space.

An inductor core includes a magnetic main body having a pillar shape and comprised of a magnetic material. The magnetic main body includes an inclined portion including an inclined surface that constitutes an outer circumferential surface of a truncated cone having an outer diameter increasing from one end toward the other end; and a straight body portion that is coaxial with the inclined portion and includes an outer peripheral surface that constitutes an outer circumferential surface of a cylindrical column body extending from the other end toward the one end, the straight body portion being connected to the inclined portion. An arithmetic mean roughness Ra of an outer peripheral surface of the straight body portion located at or around the other end is smaller than an arithmetic mean roughness Ra of an outer peripheral surface of the straight body portion that is disposed at or around the inclined portion.

Convertible writing instrument assemblies are provided, including an outer barrel having a tapered nosecone with an aperture for a writing instrument tip and a grip portion, and an aperture for receiving an eraser or a push button therethrough, wherein the writing instrument assembly provides selective access to a volume defined by the outer barrel, and wherein the outer barrel and the volume are collectively configured to operably and interchangeably receive a mechanical pencil insert having the eraser and a retractable pen insert having the push button. Mechanical pencils and pens utilizing the convertible writing instrument assemblies are also provided, along with kits for providing such mechanical pencils and pens.

A mechanical pencil which is configured so that a rotatable cam is rotationally driven with an axis of the rotatable cam relative to a holder member stabled, and smooth operation of a rotational drive mechanism is ensured. The mechanical pencil includes a rotational drive mechanism for driving rotationally a rotatable cam according to writing pressure applied to a writing lead, and transfer rotational motion of the rotatable cam to the writing lead. The rotational drive mechanism includes a holder member supporting the rotatable cam so as to be rotatable, a first fixed cam formed with a funnel-shaped inclined surface Fu and a second fixed cam formed at an obtuse angle α relative to an axial direction. Cam faces of an upper cam and a lower cam alternately meshing with the first and second fixed cams are formed along a conical inclined surface Cs.

A flexible marker includes a flexible body for gripping, and a marking implement carried at least partially within the body. The body is flexible to conform to the grip preferences of a user. The body has two parallel lateral sides and a first longitudinal end defining a central apex from which the marking implement can be extended. The body can be folded along or near a central longitudinal axis to bring together two lateral sides. The body can be folded along a first laterally extending axis in a first configuration in which the marking implement extends longitudinally beyond a second longitudinal end for use of the marking implement. The body can be folded along a second laterally extending axis in a second configuration in which the second longitudinal end extends longitudinally beyond the marking implement.

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.

An improved hand held pen holding sleeve comprising a rigid barrel with a through bore abutting a deformable finger grip element also with a through bore. The pen holding sleeve is devoid of an ink reservoir or ink cartridge. The through bore of the pen holding sleeve is sized and configured to accept disposable stick pens and common pencils as the refill element. The deformable finger grip element is removable from the rigid barrel. The deformable finger grip element, formed of an elastomer, is the sole means for capturing and retaining the refill element within the pen holding sleeve.

A writing, drawing, marking and/or cosmetic device, wherein the device includes at least one shaft and at least one inner body, wherein the at least one shaft is formed from concrete-containing material. The shaft at least partially surrounds the inner body. In the installation position the shaft is secured in an axial direction against axial displacement by a closing cover and a front part and a prestress is formed in the shaft in the axial direction via the closing cover and the front part.

Thermoplastic molding composition comprising (A) 40 to 80 wt.-% SAN copolymer (S/AN-ratio 78:22 to 65:35, Mw 80,000 to 250,000 g/mol); (B) 20 to 60 wt.-% SBC block copolymer (monovinylarene 61 to 64 wt.-%) comprising conjugated diene/monovinylarene tapered polymer blocks; and (C) 0 to 5 wt.-% additives and/or processing aids (C); exhibiting ultra-high melt flow with good mechanical, thermal and optical properties, a process for its preparation and its use for the production of bulky and/or thin walled articles.

Provided is a self-made LED luminous floating oil pen, including an empty pen tube. One end of the empty pen tube is threadedly connected to a plastic shell, and the inner cavity of the empty pen tube is filled with a mineral oil. Two sides of the inner cavity of the empty pen tube are provided with LED lamp beads distributed at equal intervals, and floating action figures are arranged in the inner cavity of the empty pen tube. Glitter and hollow plastic balls are filled in the inner cavity of the empty pen tube.
