My thanks to Diane for kindly sending me some Black Pearl erasers in June.
Compared to the other black erasers we have looked at, which were all roughly block shape, the Black Pearl is distinguished by a flattened oval shape. Just for this alone, I like it. It is portable, easy to grip, and works well.
It seems harder, and a bit denser, than other black erasers. Perhaps this is a manufacturing requirement for a thin eraser.
Just how well does it work? I used the same Rhodia pad and Staedtler Mars pencil as in the previous review, and have added a Palomino pencil.
It erases not quite as well as the Papermate Exam eraser. The softer erasers seem to have an advantage with this particular graphite/paper combination.
