The Koh-I-Noor Progresso Extra Thick Pencil range is extremely popular for sketching. Their jumbo size and extra thickness gives greater coverage. They are completely woodless and have a paper sleeve to keep your hands clean. Available in 4 grades. 1cm wide.
These are a boon to any graphite artist. Anything from the finest line to chunky shading can be achieved, and they are very comfortable to hold. I would highly recommend these pencils. Sylvia (Surrey) on 16 Mar 2009
Covers large areas well. I produce small quantities of powder by grinding on a sand paper block then blend out with chamois leather or untreated tissue. Stuart Heathcote (BELPER, United Kingdom) on 28 Jan 2013
Nice feel but would like in a harder lead which would leave a lighter impression for penciling in the water color sketches. Patricia Jennings (Paris, France) on 5 May 2012
