The idea of the format 5000 multicolored tiles is pretty good. you have a wide range of colors and shades you can test as you wish. But (there is always a but) they are not sorted and I not tell you when you are looking for a specific color of a pile of 5000! (At least sort by color group, black gray, red oranges etc.SVP!) But that's not the worst (but second), it is rather that the quantities vary greatly colors. You have 100's of gray / black, red / orange, white .... But that 30 yellow and barely more green .... Especially since I had previously bought the color chart for the same brand and there has colors that I'm still looking (...) - I still have about 500 tiles in Sort-. Overall, the product is pretty good, but (3rd and last) and sort the kind made in colors that are nearly equal amounts and the product would really TOP!
