GANSAI TAMBI is traditional, Japanese watercolor, developing colors that are based off of those seen in nature. Colors are vivid and opaque, and pans are carefully fill so that the paint is smooth, rather than granulated, and dries with a slight sheen. Individual pans are replaceable. Gansai Tambi Pans are much larger than typical watercolor pans, giving you the ability to use both small or large brushes quite easily.
