What is wrong with cheap erasers
A cheap eraser turns yellow. After a few months in a drawer it becomes hard and sticky. When you use it, it scrubs instead of erasing, leaving an orange smear. You throw it away and buy a new one.
The Staedtler Mars plastic does not do that. It is made from soft PVC that retains its properties even after years in a drawer. It crumbles neatly into small rolls you can blow off your paper.
Fifty years, unchanged
Staedtler introduced the Mars plastic eraser in the 1970s. The design has barely changed since: the same white rectangular block with blue wrapper, the same dimensions, the same material. At drawing schools and architecture firms it is the standard.
How it works
The Mars plastic picks up pencil marks without damaging the paper. It leaves no residue, does not yellow and stays supple as long as it is not exposed to direct sunlight.
