Bau Balcony BoxThe Ferm Living Bau Balcony Box borrows its expression from the uncluttered lines and industrial surfaces of the classic Bauhaus architecture, giving your balcony a vibrant and classic look. They are easily mounted on a rail with the two hooks and its metal bracket to make sure it hangs steadily. To give your plants the best care the boxes have a smart drainage system at the bottom, and the metal has a special treatment to make the boxes weatherproof.
