Drawings can be smudged just as with pastel crayons, so need to be fixed afterwards. The 60 bright colours contain a high proportion of pigment they are highly light-fast and do not change colour appreciably when fixed. The compact pastel lead is perfect for hobby painters and professional artists, because it produces plenty of colour without being used up too fast. The wood-cased PITT pastel pencils are clean to handle. The practical pencil form is easy to control, even for beginners to pastels. Faber-Castell PITT pastel pencils are particularly suitable for lines, hatching, and very fine colour transitions, but also for shading larger areas. They are useful for sketches and studies, portraits, still lifes and landscapes. High quality pigments in unsurpassably lightfast bright colours, the leads are 4.3mm diameter. Available here in 5 tins 12, 24, 36 and 60 pencils. This tin of 60 contains the complete colour range.
