An eraser includes: a base material including a plasticizer and at least one of a resin component or an elastomer component; and a porous foam made of a resin and impregnated with the resin base material, and the plasticizer has an SP value of 8.3 or more and 10 or less.

A holder for a pencil eraser with removable bands. As the eraser wears, connecting bands are removed, revealing more of the eraser. As the connecting bands are removed, they are replaced at the rear end so that the length remains the same. When the eraser is completely worn out, a new eraser is inserted in the eraser case.

A hand-held device includes a first portion and a second portion. The first portion is engaged at least in part with the second portion while being movable in translation in an axial direction relative to the second portion. The first portion presents a first distal end while the second portion presents a second distal end opposite from the first distal end in the axial direction. A blocking device is configured to prevent the first portion from moving in translation in the axial direction relative to the second portion only when, considered in the gravity direction, the first distal end is arranged above the second distal end. The blocking device includes a chamber and a ball or the equivalent housed in the chamber.

The coating film transfer tool includes: a feeding core around which transfer tape is wound and that feeds a piece of transfer tape, the piece of transfer tape including a piece of base tape and a coating film that is provided on one surface of the piece of base tape; a transfer head that presses the coating film against a transfer target and transfers the coating film thereonto; a winding core that winds up the piece of base tape from which the coating film has been transferred; and an intermediate roller that rotates as the piece of transfer tape travels, in contact with a first surface of the piece of transfer tape fed from the feeding core, the first surface being a surface on which the coating film is not provided. A second surface of the intermediate roller is adhesive with respect to the first surface.

A handheld implement having a shaft with two shaft parts which are releasably connectable together via a plug-in coupling, with a coupling unit at each front end of the shaft parts. Each coupling unit has a slide held in a guide hole open on a face side in the associated shaft part and protrudes beyond the guide hole with a slide portion, the free end of which is formed as a latching fork that has a latching opening. The slide portion bears a latching protrusion behind the latching fork in the sliding direction. The coupling unit has a guide sleeve that encloses the slide and is guided into the guide hole counter to a restoring force, and when the front ends, having the coupling units, of the shaft parts are pressed together, the latching fork of one coupling unit is latchable on the latching protrusion of the other coupling unit.

The present invention provides devices, systems, and methods for refilling a refillable fluid applicator, such as but not limited to a refillable dry erase marker. The devices, systems, and methods of the present invention advantageously allow the fluid applicator to be refilled quickly, easily, and inexpensively, and provide the benefit of significantly reducing the quantity of solid plastic waste associated with conventional disposable dry erase markers and other fluid applicators.

Provided is a coating film transfer tool comprising an external cassette and an internal cassette housed in the external cassette. The internal cassette includes a supply portion configured to supply transfer tape having a coating film on substrate tape. A pressing and transferring portion is configured to transfer the coating film to a film receiving surface by pressing the transfer tape against the film receiving surface, a take-up portion is configured to take up the substrate tape after the coating film is transferred, and a rotation-in-conjunction mechanism is configured to rotate the supply portion and the take-up portion in conjunction with each other. The external cassette includes a button and an elastic member. The pressing and transferring portion sticks out of the external cassette by the button being pressed, and the pressing and transferring portion retracts into the external cassette by the pressing of the button being stopped.
