Diamine Red Edition Thunderbolt is a vibrant, saturated ultramarine or periwinkle blue ink known for its bright color, medium shading, and occasional coppery sheen. It behaves well as a standard, clean-writing ink with average flow, low feathering and bleeding on quality paper, but low water resistance makes it wash off easily in ink wash techniques. It suits everyday writers, calligraphers, and sketchers seeking a bold, beautiful blue without extremes.
