I just did some eraser...

I just did some eraser comparisons. The NP Mono came out dead last in all tests
against W-Foam, Staedtler Mars Plastic and Campus 2B. C2B blew the others away
in every regard. The NP Mono was the only one that left traces of lead behind on
every test. The Staedtler did not fare too much better, and that was my previous
go-to. The W-Foam was pretty good, and certainly the best at generating one long
thread of spent rubber. The 2B is far and away the best one. This little NP Mono
isn't especially good.
One caveat - I tried this only with 4B lead.
