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 PVC-free.

Faber-Castell PVC-Free erasers do not contain harmful phthalate plasticizer. Phthalates have been reported to cause several undesirable effects when exposed to the human body.
