While the idea of having double-sided 3x5 cards (one side ruled the other blank) is a nice idea I didn't care for the color choices: purple blank/teal lined; orange blank/icky green lined; pink blank/yellowish lined. The only true colors were blue blank/red lined and even then the red was reddish. I'd like to see true primary/secondary colors or pastels or primary/complementary colors. However if you're just wanted to have a wide choice of colors without buying a lot of separate packets this is a good choice.
