RE-STORE modular cardboard shelf system is a simple, durable and affordable eco-friendly storage solution. Design is made to enable flat-pack trasport and easy assembling. Although made from corrugated paper board it is extremely durable and lightweight. Rigidity of construction is achieved by crossing the direction of cardboard “waves” in assembly – similar to the approach used for layering the veneer in plywood. Production of RE-STORE is highly efficient using standardized paper industry machinery and processes. One module (box) is fitted within A0 press size with almost zero waste. The packaging envelope is designed for double function: during transport and storage it protects the contents and during assembly it serves as a connector for vertical stacking.
