The Zig Memory System Brushables Marker features two brush tips, one a popular color from the Zig Memory System range and the other being a 50% tint of that color. With this unique quality, it is ideal for brush layering effects and for creating two-toned coloring effects with cardmaking, in coloring books, or when rubber stamping! Water-based pigment ink is lightfast, acid-free, archival quality, water- and fade-proof, and will not bleed through most papers.
