To be honest, the only eraser I have to compare this one to is the Staedtler
Mars, but it leaves the Mars in the dust. It erases way better, it's smudge
free, it doesn't grab the paper, and it rolls up the residue into neat little
strings making it a lot easier to clean up. I only wish I had gotten more than
one because it's on the softer side, and I can't see myself needing $25 worth of
pens and erasers any time soon!
