dualtip

Dualtip refers to a drawing instrument that houses two distinct nibs or tips in a single body. The typical configuration pairs a fine tip for precise lines with a broader tip (broad, chisel, or brush) for filling, shading, or expressive strokes. In practice, dual-tip markers and pens marketed as dual-tip or two-nib tools are used by illustrators, designers, and hobbyists to achieve varied line weights without switching instruments.

Construction and ink: Most dual-tip tools use disposable value markers or refillable systems. Tips are made from felt or nylon fibers and are designed to resist fraying with multiple uses. Inks are commonly water-based for easy blending and erasability on appropriate papers, or solvent- or alcohol-based for permanent, fast-drying results. Some brands offer replaceable tips or adapter nibs; storage caps protect tips and prevent drying.

Uses: Common applications include line art, lettering, shading, and color blocking. The fine tip is used for detail work, stippling, and crisp outlines, while the broader tip creates bulk color fields, calligraphic strokes, and smooth gradients. Artists often employ layering and blending techniques to integrate marks from both tips.

History and market: Dual-tip instruments emerged as a practical solution for illustrators seeking versatility. While the exact origin is hard to attribute, such tools gained prominence during the late 20th century within craft and manga-art communities, and remain widely available in art-supply catalogs and online retailers today.
