Sharpie Liquid Pencil features innovative Liquid Graphite Technology that eliminates broken leads. Pencil also offers a hassle-free, uninterrupted writing experience by eliminating the need to load and reload leads.

Part of the barrel is transparent so you can monitor your "lead" supply. Design also features a retractable tip, soft comfortable grip, eraser and clip to attach to notebooks, pockets and more. Pencil is certified AP nontoxic.
