And I learned early never to buy a gross of pencils. Erasers become
calcified and petrify before the -first- dozen is used up, so I get a
box every year at the back-to-school price of five cents.


I was reading a bout a better grade pencil that touted that it had genuine
natural rubber for the eraser IIRC.

Is there a difference in longetivity that you know of?

I recall using a white plastic eraser while I was taking drafting classes.


White plastic is still the best. You can get them in a pen type thing that
fits well in an apron pocket. At work, my upper apron pocket always contains
two scales, a pen, mechanical pencil and an eraser.
