The Super Pencil is 100% solid writing material (compared to a conventional carpenter’s pencil which is 90% wood and ground off so you can use it). With the Super Pencil, you can mark without sharpening. Whether you want a fine line or a wide line, the Super Pencil is ready and waiting. It lasts 7 times longer than the conventional carpenter’s pencil and is made from a non-toxic graphite composite which is smudge and water resistant. Made in USA.
