Product Overview
Derwent Onyx Pencils are made from smooth dark graphite and allows you to instantly create dense rich jet-black tones, even darker than a Graphic 9B. Its 4mm wide core has a non-crumbly texture which will sharpen and hold a fine point for longer. Blend it with your finger tip or a Tortillon. Equally good for quick expressive sketches as well as detailed technical and architectural drawings.
