Eraser Cap (two-pack)
The Grip Eraser Cap sits on your pencil and ensures you always have a great eraser to hand; when you runs out (and they are difficult to finish), you can get another one. AND it can be attached on the rear to lengthen the pencil or on the front as a pencil-point protector.
It is Faber-Castell high quality and PVC-Free.
Try with the Faber-Castell Two Tone pencils.
