Arguably the best oil pastel around, suitable for artists. Smooth to apply to surfaces, deep, clear colour, and with high to highest lightfastness ratings. This set has a good range of useful colours. Lovely to use, and colours can be blended, e.g. yellow plus blue becomes green. Can be applied to most papers or canvas. Thinners (as for oils) can be used if wished. Sennelier has an excellent reputation.
Friend who is an excellent non professional artist, delighted with gift, impressed with oil pastel set, has not used this medium before and looking forward to it.
