What are black erasers for?

There is a 40% sale at Tombow today (1 Day/code SHOP40) and I see these black erasers...

What makes them different from white erasers? It says something about graphite but wouldnt white do that too?


TIA

As far as I know, they're the same as the white eraser - but they don't get that "dirty" look, so they're always nice and clean. Aside from the always-clean look, they're nice if you want to have an eraser for a very specific use (ex. a special eraser to use on watercolor paper) that performs the same way a white one does.

At least with the Pearl erasers - remember the Pink Pearl we had back in school? - there's a difference. White leaves more eraser dust, is the least expensive of the three, is a bit crumbly. Black is the most expensive, leaves little dust and is more ergonomic.

I don't know if other companies' black erasers are manufactured from the same materials or not.
