With everything that you need to write down for a costume - materials, colors, and notes for each part - the easiest way to organize it is with color. The BIC® 4-Color™ pen includes 4 fun colors - black, blue, red, and green. This makes it super simple to distinguish your notes, color coordinate, and express whatever you want. BIC® has created unique personalities for each of the colors in the pen that you can get to know in the videos below (I'd definitely say I'm most like Green - he's a social network loving foodie!).
