At Think Outside our ongoing design direction is focused on the use of recycled and natural sustainable materials, being metal, wood, rubber and stone. Please note; our artisans loving handcraft each piece individually from recycled and sustainable materials. Because of the use of recycled materials colors and shades may look may be different than pictured. You can therefore be confident that you are investing in an eco-friendly and unique work of art. If using outside please treat material first (Rust-Oleum Stops Rust).
