Dieter Rams often said that “good design is as little design as possible.” Apparently someone at Levenger paid attention to that morsel when they came up with the Circa Notebook system. Essentially, Circa is a unique way of organizing paper documents within a single notebook, which allows for pages to be rearranged, removed, and even inserted. In other words, it’s not only a way to get organized, but it ensures that you stay organized.
The system hinges on a special variation on a standard hole punch. Rather than the three-hole punch for binders, the Circa punch creates a toothy pattern along the edge of each loose piece of paper. Instead of a spine, the Circa notebooks are held together by a series of discs which fit perfectly in the grooves left by the punch. You are then left with pages that you can insert and remove without any tears or trauma to the spine.
Levenger offers a wide assortment of different insert options (including a partnership with Rhodia notebooks) which are pre-punched for convenience. That said, the best part of the Circa system is the ability to punch any loose piece of paper to make it compatible.
