PanPastel Colours are artists' quality pastels, packed in a pan format (that interlock with eachother). Designed so artists can easily lift, apply & control pastel colour, just like that of painting. Made from quality pigments PanPastel Colours use a unique manufacturing process that requires minimal binder & fillers, resulting in a rich, highly pigmented, ultra soft & low dust formula. They have excellent lightfastness, are fully erasable & are compatible with traditional pastel media, surfaces & fixatives. Each pan approximately measures 2.38" (62mm) and contains 9ml of colour.
