Einfach–vielfach Blumberg Design is a modular shelving unit snapped together to meet the needs of the user. If you have good collection of books, expand it in whichever style you want. Mutably expandable, these storage modules come in four different sizes. Upright or slanted, the modules (connected by integrated clips) mount from left to right and from the bottom up. Unit by unit the shelves can then be pieced together and bolted to a wall. The rest is up to your imagination!
