The X2 Bookshelf is a fold-up shelf designed by Laurindo Marta for WeWood out of 100% solid oak. The modular design is made from two blocks that can be customized by increasing the width or height whenever you want. Each of the blocks is constructed of 48 wooden slats that work in tandem with brass screws to allow movement into another configuration.

By moving the parts around, you can create new storage compartments or increase/decrease their size to get the perfect amount of space for your books and other items you want to display.
