Like building blocks, Mini Stacked Storage Boxes are a modular system of storage cubes that can be used to display and organize your favorite objects. You can position the storage cubes horizontally or vertically, arranged in a creative configuration or in a simple grid. All Mini Stacked modules have backboards, which allows them to be used freestanding or wall-mounted. Each module comes with two clips in the same color as the module, while Oak comes with two clips in Light Grey.
