This eraser is one of the highest-tech examples on the market, combining the technology of Sakura's famous foam eraser with a firmer "hybrid matrix formula". The result is a soft yet firm eraser that works well with all pencil hardnesses, especially those in the B-2H range.
The open-cell foam works like super-fine sandpaper on the surface of your paper, bringing out everything possible from the microscopic nooks and crannies.
