These BIC Marking Fine Tip Permanent Markers are ideal for art, writing and more. You get a set of 12 in each box. These writing markers are permanent on most hard-to-mark surfaces. A silver barrel and a textured rubber grip deliver comfort and control. The fine-point permanent markers provide smooth ink flow and consistent lines. The fade-resistant, acid-free ink maintains its original bright, vivid color over time and does not cause paper to turn yellow. The quick-drying ink marks on most anything, including glass, metal, plastic, photos, foil-coated papers and oily and damp surfaces. The ink in these black markers won't dry out when the cap is left off for up to two weeks.
