To extend the lead, simply shake the pencil up and down; there is no need to let go and re-grip your pencil every time (though clicking down on the cap works too). In creating the Fure Fure line, Pilot reduced the shaker mechanism noise by about 30% compared to existing shaker pencils, allowing for a more enjoyable writing experience. The pencil also features a completely retractable tip and a capped refillable eraser. And for fun, you can customize it to be even cuter by stringing a charm through the hole in the clip!
