I use this little eraser at work. It is so much better than the usual white rectangular eraser. This works way better

I was very impressed with this product. My whole life I've been using those long white staedtler erasers without a second thought, then one day while buying some other Prismacolor products I added this on a whim!

It does a great job removing pencil, both coloured and regular, but I was surprised to find that the thing that really makes this superior is the shape. It works really well for getting into those tiny tight angles.
