I love this eraser. I got a couple from Jet Pens a while back and it is incredible. Jet pens is pretty awesome too, but this is an amazing eraser. I’m used to the click erasers and the usual Staedtler Mars plastic erasers. They don’t get all the sketchy graphite off your finished drawing. Or maybe I’m doing it wrong. With this strange black eraser though, you can’t go wrong.
