Blackwing Point Guards are designed to make sure your pencils stay sharp in your pocket, carry-on, bike bag and everywhere else. Each set of Blackwing 155 Point Guards includes: 1 matte blue, 1 matte yellow and 1 matte red Point Guard inspired by Bauhaus artist Wassily Kandinsky's color and shape questionnaire. Kandisnky believed that there was a universal correlation between color and shape, and his questionnaire yielded surprisingly consistent results: a blue circle, a yellow triangle and a red square.
