The BIC Permanent Markers work on most hard-to-mark surfaces such as glass, metal, plastic, photos, foil-coated papers, oily, and damp surfaces. The silver barrel has a textured rubber grip providing added comfort and control. The true-to-form fine tip provides smooth, quick-drying ink with fade-resistant, acid-free bright, vivid colours. | BIC Mark It Permanent Marker (BICGPM11BK) - Fine - Black
