According to the invention, it is provided that a fastening device between the inner part and the outer part serves to fasten the inner part to the outer part, which fastening device is elastically deformable and is deformed in the installed state against its elastic restoring force, wherein it is supported on one side on the inner part and on the other side on the outer part by means of the elastic restoring force to fasten the inner part to the outer part.

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.

Provided is a writing instrument including a pen cap, a pen tip and a pen barrel, wherein the pen tip is arranged at one end of the pen barrel, an ink cartridge configured to store ink is formed at the other end of the pen barrel, and the pen cap able to be removed is provided on the pen barrel for covering the pen tip; wherein the writing instrument further includes: an ink delivery assembly including a first tube body, a second tube body, a liquid guiding column and liquid absorbent cotton, wherein the second tube body is inserted into the first tube body, the liquid guiding column is inserted into the second tube body, the liquid absorbent cotton is arranged inside the first tube body, an inner end of the pen tip is inserted into the first tube body, and an end of the first tube body which is away from the pen tip is opened with a first vent and an end of the second tube body which is close to the pen tip is opened with a second vent; the first tube body is arranged in the pen barrel; an air flow channel is formed between an inner wall of the pen barrel and the first tube body; the second tube body is in communication with the ink cartridge; a part of the pen barrel corresponding to where the pen tip is arranged is provided with a plurality of ribs, and an air inlet is enclosed by the pen tip and any two adjacent ribs, and the air inlet is in communication with the air flow channel. The writing instrument could increase ink storage capacity and avoid ink leakage, thereby improving user experience.

A writing and underline-drawing implement includes: an elongate hollow body having an open top portion and a closed bottom portion; an elongate core received in the elongate hollow body, the elongate core having the tip portion; a cap having a tip hole partially formed in a top portion thereof, the cap being hollow and having an open bottom portion to partially receive and/or passed through by the elongate core, the cap being configured to at least partially move along a length of the elongate hollow body; and rotatable guide wheels coupled to the cap at an upper portion of the cap, the cap being disposed between the guide wheels.

An ink reservoir unit for a writing instruments using an ink reservoir tube with which low contamination can be achieved considering environmental problems; and a writing instruments using the same. The ink reservoir tube is composed of a composite material in which a raw material is layered on a paper substrate having paper as a substrate. One end section of the ink reservoir tube is coupled to a connection part formed on a writing member or a relay member that holds the writing member to constitute the ink reservoir unit for a writing instrument. In one preferred aspect, a locking device using a male thread formed on an outer peripheral surface is provided to the connection part to be connected to the ink reservoir tube, and the ink reservoir tube is coupled to the relay member that holds the writing member by the locking device.

Applicator (3) for applying a cosmetic or care product, which extends along a longitudinal axis (X) and has: —an applicator member (6), —a holder (5) for the applicator member, and a handle (10) that defines a gripping surface allowing the user to hold the applicator during the application of the product, the handle being deformable with shape memory at least along a part of its length.
