Permanent markers with a fine point are permanent on most hard-to-mark surfaces. Silver barrel and a textured rubber grip deliver comfort and control. True-to-form fine tip provides smooth ink flow with fade-resistant, acid-free bright, vivid colors. Quick-drying ink marks on most anything, including glass, metal, plastic, photos, foil-coated papers, oily and damp surfaces. Ink won't dry out when cap is left off for two weeks. Cap color indicates ink color.
