The quality of an eraser and using the correct eraser are crucial for optimum results. Basically, two different materials are used to make erasers: rubber and plastic. All rubber erasers and the majority of the plastic erasers made by Faber-Castell are LATEX-free. Faber-Castell LATEX-Free erasers do not contain Latex derivates. The balanced plastic mixture guarantees soft and smear-free erasing.
