I purchased this set of 36 colors for an elementary-school-age child after she almost emptied my own set of 24.  These are great markers for the price; in my opinion they are substantially better than any marker product Crayola makes.  The colors are vibrant and lay down smoothly; you can even blend by overlaying colors (a technique which takes practice but can be very rewarding).  There is a good range of colors in this set, with several different shades/tints/hues in each color family (i.e. you get four or five shades in the red-pink family, five or six in the blue-gray family, and so on).
