Paintstik Oil Colors are self-sealing; just peel off the film before using. It will reform on the stick in a matter of hours, so the sticks never dry out. There's no mess and no running color, just solid, easy-to-control sticks of oil color that can be spread or blended with the finger, brush, or palette knife. There are also no unpleasant odors or fumes, so you can paint virtually anywhere, at any time.
Paintstik Oil Colors work on almost any surface: canvas, paper, wood, plastic, metal, glass, and glazed ceramics. They're also great for stamping, stenciling, and fabric decorating!
