There's no "right" way to use them because all sides measure the same! Connect them in any way you like. Cubo storage cubes can attach together in any direction, which opens up a myriad of new design possibilities. This innovative set of 3 storage cubes by Niche are designed to fasten together in any direction! Cubes connect to one another with spring pins, making it easy to customize and create a storage system just for you with a single cube to a set of 12 or more. No more searching for the right size screwdriver or dropping tiny screws.
