An eraser for removing strokes of writing, painting and/or drawing tools, including at least one binder and at least one plasticizer. The eraser includes at least one plasticizer in the form of pentaerythritol tetravalerate.

An eraser for removing strokes of writing, painting and/or drawing implements, including at least one binder and at least one plasticizer, wherein the at least one plasticizer is a polyol ester.

Provided are an erasing member which is excellent in erasability for handwritings written by means of a pencil, a mechanical pencil and the like and which does not produce eraser dusts, and an erasing tool in which a part to be erased can be visually recognized in erasing.The erasing member comprises a blend composition containing a liquid-absorbing porous material, and a basic magnesium carbonate porous material and the like can be used as the liquid-absorbing porous material. And in an erasing tool in which an erasing part is formed at one end and in which a transparent or translucent visible part making it possible to visually recognize a writing surface is provided in the vicinity of the erasing part, the erasing member described above is mounted to the erasing part, whereby the erasing tool which does not produce eraser dusts is obtained.

There is an erasing tool having a polyetheramine for erasing a thermochromic ink composition capable of undergoing a color change that cannot be reversed by application of a temperature change. There also is a writing instrument having a thermochromic ink composition and an erasing tool. Finally, there is a method for irreversibly erasing a written line made with a thermochromic ink composition and erased with an erasing tool.

Provided is an erasing tool which produces no eraser crumbs and allows a progress for adsorption of even a light color of color pencil leads and the like to be recognized at a glance and which makes it possible to surely erase the color of color pencil lead and has a high light transmittance. The erasing tool is characterized by containing a secondary aggregate having a diameter of 1 to 100 μm with a petaloid particle as a primary particle.

A moldable eraser kit includes a first silicone polymer, a second silicone polymer, an abrasive agent, a catalyst configured to catalyze a reaction between the first silicone polymer and the second silicone polymer at room temperature, and at least two containers such that the first silicone polymer, the second silicone polymer, and the catalyst are not all present in the same container. Also disclosed herein is a method of making an eraser including the steps of mixing a first silicone polymer, a second silicone polymer, a catalyst, an abrasive agent, and optionally one or more additives to form a mixture, the mixture being free of polyvinyl chloride. The method also includes molding the mixture to form a shape and curing the mixture in the shape at room temperature to form a molded eraser.
