Pentel Arts Oil Pastels are brilliant, fade-resistant colours. The creamy softness of these pastels makes them easy to lay down & produce varying textures. The slow drying time means you can work on a piece for several weeks. These pastels apply smoothly and blend easily using cotton buds, fingers or tortillon / paper stumps for subtle shades, tints and colour mixtures. Pentel Arts Oil Pastels are easy to use for artists of all ages, beginner to advanced. Also great for the office, home & school. These bright, smooth and fun oil pastels are available in various colours in different assortments. They are great to use in conjunction with watercolours, oil paints and soft pastels. Pentel Oil Pastels are ACMI Certified and acid-free pastels that are ideal for use on most types of paper (including pastel, watercolour, cartridge, craft etc.) as well as canvas, oil and acrylic boards. They are an exciting medium for the creative mind, more vivid than chalk pastels and more resistant to the effects of humidity for longer-lasting drawings.
