These vibrant Metallic Leafing Pens contain smooth flowing paint for high quality metallic accents. The unique chiseled tip can draw both thick and thin lines on many different surfaces. The acid-free, highly saturated metallic paint in each pen can draw on wood, metal, glass, plaster, ceramic, craft foam, fabric, and more. Paint dries to the touch in 10 minutes and is ready to handle in 2 hours.
So my only real complaint is that it is hard to use with stencils because it tends to fuzz and bleed under without creating a crisp line. Other than that I like it.
