Speedball reformulated their India Ink line from the ground up, maintaining the performance characteristics artists rely on while expanding into twelve vivid colors. Shellac-free formulation achieves deep opacity and brilliant color saturation without the traditional brittleness that causes cracking on flexible surfaces. The ink flows smoothly through dip pens and technical drawing tools while maintaining enough body for direct brush application, essential for calligraphers switching between pointed pens and broad-edge work within a single piece.

Each color dries fully waterproof, allowing successive layering without reactivation. This permanence matters for mixed media artists building illustrations that combine ink linework with watercolor washes, or journalers adding painted elements over written entries. Optimized fluidity means the ink doesn't flood or feather on quality papers, yet releases cleanly from nibs without requiring constant wiping.

The eleven-piece set provides practical color exploration: ten 12ml bottles spanning black through jewel tones, plus an ink well palette for convenient access during active sessions. Individual bottles let you stock deep on colors you use constantly, Black Velvet for linework, Satin White for highlights on toned papers, or specific hues that define your illustration palette.
