The present invention relates to a scratching device and in particular to a scratching device having an integrated light. The scratching device is a tool having a first end and a second end. A stylus and a retractable writing element can be at the first end of the tool. A scraper is at the second end of the tool. The scraper has first and second sides that can converge to form an edge. The scraper has an interior that encases a light. The light is diffused through the scraper, wherein the edge is illuminated. The first side of the scraper can be concave, and the second side can be convex.

A retractable writing instrument has a marking component for marking a writable surface. A barrel houses at a portion of the marking component, as well as an extension/retraction mechanism. The barrel has a slider portion. An internal magnet is adapted to operate the extension/retraction mechanism and positioned for operating movement along a length of the slider portion for extending and retracting a portion of the marking component. A slidable magnetic ring has an inner diameter for receiving the slider portion and is adapted to magnetically cooperate with the internal magnet.

A portable kit for storing a pen according to the present invention includes a base in which an accommodation portion is famed. The pen is fastened to the accommodation portion, and is coupled to a coupling kit having a shape corresponding to that of the accommodation portion and accommodated in the accommodation portion. A grip portion is formed on the coupling kit, and allows the pen to be withdrawn from or retracted into the base in such a manner that the grip portion is pushed with a finger.

A rotary feeding mechanism for axially feeding a rod-shaped body from a main body by rotating a tapered tip has a simple structure and can be produced economically. The main body is provided with plural open windows are arranged at a predetermined thread pitch along an axial direction of the main body. The tapered tip is installed rotatably on the main body, and a guide pipe extending toward the inside of the main body is fixed to the tapered tip. A holder for holding the rod-shaped body is housed in the main body, and the holder and the guide pipe are connected non-rotatably and movably in the axial direction. The outer periphery of the holder has an external thread which engages with the windows so that when the tapered tip is rotated, the holder moves in the axial direction while rotating via the guide pipe, and the rod-shaped body can be projected from or retracted into the main body.

An application container includes a main body cylinder, an application tool, and an engagement portion. The main body cylinder has a first end and a second end opposite the first end. The application tool is insertable into the main body cylinder through the first end of the main body cylinder. The engagement portion is positioned within the main body cylinder, and includes a cylindrical portion to connect with the application tool and a connector that connects the cylindrical portion and the main body cylinder. The cylindrical portion of the engagement portion is spaced apart from the main body cylinder.
