Pentel White Pencil Eraser Caps
As a lover of sudoku and kenken puzzles I'm often looking for a pencil with a good eraser. Wood and graphite last forever, but rubber not so much, and so our house has dozens of pencils that lurk in drawers, waiting to cause occasional bouts of frustration for anyone who tries to erase with them. Bought a package of these recently and they've restored life to them all. These have same premium feel of high end mechanical pencil erasers.
