This elegant, glue- and tool-free storage system made me look. Tokio born and Danmark based designer Yukari Hotta created these simple shelves, called Kile, that can be assembled without any tools or toxic adhesives. Just interlock the components and secure them with wooden wedges. Made from an eco labeled wood board material, the piece is sleek and minimalist. A variety of soft colors allows you to play with different combinations while customizing the unit. And because the furniture can be disassembled in seconds, it can be easily stored. All components are shipped flat, which adds to the eco-friendly pedigree of the product.
