Poppy red Fabrico™ markers can be used on a variety of surfaces, including fabric, paper, wood, leather, unglazed ceramic, paper mache and shrink plastic. Each marker features a brush tip on one end and a bullet tip on the other. The brush tip is ideal for coloring in, and the bullet tip is perfect for lettering and adding details. Both tips are specifically designed for smooth ink flow. Heat-setting is recommended for added permanence. Store horizontally to keep both tips well-inked.
