I found the Way Basics maker store at Zazzle today. If you're looking for custom book shelves or storage units, check out what they have to offer. You can pick different colors for the different boxes (modular storage cubes) to create a unique set up. "The Way Basics Small Modular Organizer is the perfect storage solution for any household need. Minimal in design, this deceivingly simple oh-so-basic box holds limitless possibilities!"
