The DUST-Free erasers for Faber-Castell writing pencils and crayons produce less debris and do not contain harmful phthalates. Phthalates have been blamed for various side effects when they come in contact with the human body. However, phthalates are still widely used in the production of erasers around the world. The balanced texture of the DUST-Free erasers guarantees a smooth erasure, without smudges.
