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.

It's basically the eraser I grew up with and used in all my math classes in grade school and college, but more earth-friendly! No other eraser compares.

This is a really good eraser! It's small but it's a good way to try out the product before buying the larger size.
