55ml Spirit of Petroleum Holbein

Spirit of Petroleum is a refined petroleum oil best suited for thinning out colors. It provides a smoothness in application similar to watercolor painting. Highly volatile, it evaporates quickly after drying, leaving a dull matte finish. Ideal for all work from rough sketching and underpainting, to finished professional painting. In a 55ml bottle.
