I got this at an amusement center! These are pen-type crayons that allow for color mixing with water♪ It's a set of 36 colors. Features: * Mixable colors * Vibrant color payoff * Smooth writing feel * With caps * Retractable pen type They're crayons, but because they're water-based, you can use them like watercolors. I used them only once, though I can't remember which colors.
