Karin DécoBrush Metallic Markers are ideal for making metallic marks on both dark and light papers and other surfaces. The markers feature durable, flexible tips, and Karin's proprietary "liquid ink" technology that maintains the ink color down to the last drop. When dry, the ink is permanent, light-resistant, and waterproof on paper, wood, ceramics, glass, metal, and plastics — great for drawing, writing, calligraphy, brush lettering, and more. Every DécoBrush Metallic Marker contains 2.4 ml of acid-free, non-toxic, metallic ink.
