The Odu container system consist of cubic drawer units that can open into four directions. You can build your own formation with the modular cubes to reach the drawers' content from any direction.

There are positive and negative bumpers in the drawers which manage how far can you pull it out and also can help finding the center position:

When you lift up one Odu, the drawer sink down a little bit which locks the drawer. It avoids that your stuff can fall out of the drawer while you carry an Odu from one place to another.
