Brushables ZIG Brushables have two brush tips and two tones per marker, one color from the ZIG Memory System color range and the other color being a 50 percent tint of that color. Brushables are featured in the ZIG Memory System line making them a water-based pigment, permanent, lightfast, acid-free, and even photo safe; most suitable for paper. This unique two-toned pen is great for brush layering techniques and for creating two-toned blending effects. With a flexible felt tip and strong elasticity, Brushables are even great for brush lettering. Use ZIG Brushables to blend with any colors from the dual tip Memory System markers, prefect for card making, coloring books, scrapbooking and even rubber stamping.
Blending Tips: Taking two ZIG Brushables, for a few seconds gently touch nib-to-nib. Keep the two pens horizontal and ink will flow from the top pen onto the tip of the second pen. After using the blended pen, clean excess ink off onto a piece of scrap paper or towel.
Keep stored horizontal.
