  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.
