A novel blending stump pencil device that provides a user with one implement for both drawing and blending. The device comprises a wood-bodied pencil with a blending stump attached to a rear of the pencil via a securing apparatus. The device comprises a clear finish and a removable plastic sleeve that protects the blending stump from damage and debris. Further, the device can be included in a kit with multiple pencil types.

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.

Provided is an electronic pen with a cylindrical housing including an opening at an end portion of the housing on a pen tip side of the housing, a cylindrical member disposed in the housing and fixed to the housing at a part on the pen tip side of the housing, and a core body formed in a rod shape by a material containing a pigment, the core body including a body portion inserted into the cylindrical member through the opening of the housing and a pull-out portion configured to enable the core body to be pulled out of the housing. A diameter of the body portion of the core body inserted into the cylindrical member is larger than a difference between an outer diameter of the cylindrical member and an inner diameter of the cylindrical member.

A clip comprised of removably attached components. The clip may be attached to a writing instrument, such as a pencil, or stylus. The surface of the clip has male elements that allow the components to snap on to the clip so that the clip may be adorned. The components are secured to the clip so that they may rotate freely around the male element. The components may be comprised of decorative elements, such as jewels, initials, logos, or pictures. The components may be comprised of a utilitarian element, such as a lanyard, or a flashing light to indicate an incoming email. The components may have a tactile surface comprised of bumps, or waves. The components may comprise of movable elements such as a rolling ball, or star that spins. The tactile surface and moving elements of a component may aid in the treatment of anxiety and attention deficit disorders.

Disclosed is an electronic mechanical pencil including: a first body part for accommodating a mechanical pencil cartridge for enabling writing through a mechanical pencil lead provided therein, a camera module capable of recognizing a user's writing through the mechanical pencil cartridge, a board part connected to the camera module, a power supply part for supplying power to the board part and the camera module; and a second body part for accommodating a push button part for drawing out the mechanical pencil lead from the mechanical pencil cartridge, and a pressure sensor part coupled to a lower end of the push button part and capable of coming into contact with the mechanical pencil cartridge in order to detect pressure of the mechanical pencil cartridge against a paper, wherein the first body part and the second body part are separated from each other in order to refill the mechanical pencil cartridge.
