The Pilot Fure Fure Sprinter is one sleek and stylish shaker pencil! The name "Sprinter" has two meanings: speedy writing due to the shaker mechanism, and the sporty look of the bi-colored black/silver design. In creating the Fure Fure line, Pilot was able to reduce the noise of the shaker mechanism by about 30% for a more enjoyable writing experience. Simply shake the pencil up and down to extend the lead; there is no need to let go and re-grip your pencil every time (though clicking down on the cap works too). You can also string a charm through the hole in the clip to customize it! The pencil also has a capped refillable eraser.
