Use them. Marvel at them. Just don't lick them. No matter your notation needs, ensure that even the smallest stuff gets noticed with Keep It Simple Stickies - just as colorful and witty as all your brilliant (or mundane) thoughts. Knock Knock was founded in 2002 by Jen Bilik with the mission of creating witty, design-driven gift products and books, along with anything else that might strike the Knock Knock fancy. Our products aspire to bring humor, function, organization, and aesthetics to everyday life. We believe that people are intelligent enough to appreciate wit, wordplay, and conceptual thought. Whether we re producing sticky notes or a volume of thoroughly researched nonfiction, we strive not to dumb down as we create. Our sensibility remains proudly distinct.
