Sounded thin. You made me check. My eraser shield, probably from the
'60s, seems to be .0051" . (I have no way to measure just the areas
close to my most frequent mistakes -- maybe a bit thinner.) Another case
of the cheapening of modern products?
Hmm. Just noticed there is a very slight cylindrical curve to the
device. I was never instructed about that, or forgot, seems the proper
application would be convex down?
