Works great for small errors.
I had a variety of little white mechanical pencil erasers, but they were all too
big.These fit my M-301 perfectly.
I rarely erase. In fact the original eraser lasted two years, until I gave it up
to girl who lost her ear ring backer, Still, I soon had a calendar entry that
needed erasing, So I turned to Jet Pens, since I could not find the erasers
anywhere else. All the stores had fat erasers only.
