Ecoline Plastic Set 10×30 ml is a transparent dye-based liquid watercolour set designed for illustration, design, calligraphy, and expressive painting techniques. The colours are highly vibrant and can be diluted with water to create lighter tones or blended for smooth gradients and transitions.

The ink remains water-reactivable when dry, allowing for continued reworking and layering. This set includes Lemon Yellow (205), Light Orange (236), Vermilion (311), Magenta (337), Ultramarine Violet (507), Sky Blue / Cyan (578), Green (600), Sepia (416), Grey (704), and Black (700), and is suitable for use on paper, illustration board, and cardboard.
