So, I would say that the "Dust Catch" feature makes a quicker job of erasing.

Tombow Mono Dust Catch Eraser, single pack for $2.24

The dust catch eraser makes a few tiny balls that are easy to remove and don't make a mess

The dust catch feathre is also very nice

The Mono Dust Catch does leave less dust than other erasers

Tombow's Mono Dust Catch Eraser does exactly what it claims

My first use was the pen style called MONO ZERO in both round and square tip which are used to take away graphite to “draw” in a subtractive manner as well as for typical erasing of unwanted marks in a drawing

In our household, erasers are a hot commodity as we erase a lot - between homework and artistic endeavors, there's always a use for an eraser here
