The Faber-Castell 185100 sanding block consists of fine and coarse grit sandpaper strips mounted on a solid wood handle. It allows you to sharpen and shape graphite pencils, compass leads, craft charcoal, and pastel sticks into bevels or conical points. By passing the lead over the abrasive surfaces, the artist achieves precise control of the point without breaking the material. Indispensable in the kit of draftsmen, architects, and fine arts students.
