The Grip rubber cap is one of Faber-Castell's innovations and serves not only for erasing but also as a pencil protector or its extension when it becomes too small. The rubber is high quality like the other tyres of Faber-Castell and does not contain PVC. It is available in three colors: gray, red and blue.
One pack contains 2 rubber caps.
For black-graphite pencils.
It wipes off without staining.
