Shiva Artist's Paintstiks are oil paint in a crayon form. They are made of wax, a small amount of low-acid linseed oil, and pigment. When the paints are not in use, a thin film or skin forms over the paint and keeps the paint from drying up. These paint stiks can be use directly on fabric or paper and can be made permanent once heat set with an iron. They are available in matte and iridescent colors. You will find the iridescent colors available here.
