Inspired by old school theme paper notebooks from the 1980s, the new INVISIGRID Loose Leaf Notebook has some unique features that set it apart from ordinary loose leaf paper.
Vertically, the line spacing is somewhere between wide-ruled and college-ruled, where the space between three lines is equal to 1 inch. Horizontally, the lines feature small gaps that break the line into 1/3" segments, which are equal to the vertical distance between each of the lines. This creates an invisible vertical channel of negative space which can serve as a guide for creating tables, graphs, diagrams or any other rectangular configuration. This type of 1/3 inch ruling more closely resembles the standard wide-ruled format, but with the added bonus of an extra line per side. The second feature that sets the Koala Tools Loose Leaf Notebook apart is the light blue tinted paper. The soft blue hue is nearly imperceptible (unless contrasted against a stark white sheet), but adds an aesthetic touch that will surely be to the delight of many stationery aficionados. Third, we made the three holes smaller to reduce the wiggle that the sheets would have when locked into a 3 ring binder. Lastly, we put it all together into a convenient tape bound notebook, where individual sheets can be conveniently and neatly removed from the notebook if desired.
