The Theory

The textured covers of these notebooks have the feel of old textbooks, and with advanced lay-flat pages, they want to fall open, like a well-loved library book. Go ahead and see for yourself – these are the notebooks your most brilliant ideas, sketches, and illustrations have been waiting for.

The Theory series is built with extra-thick, high-quality 100% recycled paper and printed with soy inks, leaving a light footprint. Be inspired to ask the right questions, find creative solutions to complex problems, and beauty in the little things.
