For me, it is the best set of "professional amateur" 24 watercolors available in the Greek market. Variety of colors; there is purple, Payne's grey, white, and black, essential colors that are missing from many "more famous" sets. They activate instantly and have durability. Both the lid, which is easily removable, and the main body of the case (after removing the color tiles) can be used as mixing palettes. Ideal size for travel, the plastic is easily cleaned with water and then eraser for any color stains. The brush can be replaced with a better one. It's worth every euro and it gives me great joy to express myself with this specific set from Daler Rowney!
