Able to be used individually or in conjunction with traditional oil colours, enjoy a greater sense of spontaneity & approach oil painting differently with the Extra-Fine Oil Stick range from Sennelier. Made using pure, highly concentrated pigments with safflower oil & high-quality mineral wax, these incredibly versatile sticks can be layered on one another or thinned using a solvent for smoother blending & gradients. Comparable to traditional oil colours, they're touch dry in 2-4 days (dependent on thickness of application) & able to be varnished with most conventional finishes after 6 months. The sticks feature a fine protective film that must be removed before use & will re-form if not used.
