The Best Pencil Eraser
Mars plastic erasers (4-pack, $6) are the best. Abrasive erasers tear up the paper surface too much, and unless you have mastered pressing really hard without breaking the lead a mechanical pencil doesn’t draw that deep anyway.
The plastic erasers can also be cleaned with a wet thumb or a rub on scrap paper for neat work. I always find the “gritty” or “gummy” erasers get so dirty you spend half your time rubbing out their own mess. The Mars compound is stiff enough that corners can be used for fine work, or large areas erased with the flat end. The dirty, used portions just roll off as you use it and are cleanly blown/swiped away. I like the idea of putty/moldable erasers, but they get filthy, crumbly and horrible if kept in a pocket or bag.06/7/19
