Review on Kuretake GANSAI TAMBI Watercolor Paints - Handcrafted, Professional-Quality Pigment Inks for Artists and Crafters - AP-Certified - Blendable - Show up on Dark Papers - Made in Japan (24 Colors) by Leanne Young

I think this is a great product for the price I paid (about $24). Keep in mind that this isn't the kind of art-quality paint that Winsor and Newton, for example, make, but their paint also costs more than five times as much. For what it is, it's wonderful. Are the colors rich and cheerful, are they lightfast? I can't say, I suspect they may not be, but it won't affect many people. Don't leave artworks that are important (to you) out of direct sunlight and you'll be fine. Regardless of the quality of the paint, it is not recommended to expose artworks to direct sunlight. Note: Work with acid-free paper if you want your work to last longer without yellowing the paper.
