Caran DAche GRAFCUBE Graphite Blocks
Caran d'ache Grafcube Graphite Sticks are a piece of compressed solid graphite in a cube shape. It is available in two different thicknesses, 10mm & 15mm and comes in a range of degrees (3B, 6B, 9B) to produce different graphite tones.
These Graphite Blocks are perfect for creating quick, dramatic sketches and atmospheric line drawings.
Use Grafcubes to add large amounts of solid graphite and tone to large format drawings. Use the side of the stick to add large areas of tone and the edges of the stick for fine lines.
These are great for adding shadow and light to your sketches as the graphite blends very easily.
