Fabrico Dual Marker 182 Real Black
are permanent dual-tip fabric markers. Use the brush tip for paintbrush-like strokes and to fill in larger areas, and the bullet tip for detail work. They can used for stamping and scrapbooking as well as on fabric.
These markers work on fabric, wood, leather, unglazed ceramic, paper mache, and shrink plastic. They are acid free, fade resistant, archival quality, and they conform to ASTM D-4236 and F963-95.
What's more, they do not require heat setting (although for greatest permanence on fabric we do recommend heat-setting).
These markers should be stored horizontally.
