Naturescast products are made of reclaimed dead trees, limbs, twigs and leaves found on the forest floor compressed with an eco-friendly water based binder. These great outdoor designs mean nature's cast-offs (see, we figured out the word play of their company name!) help to bring new life to the outdoors. The designs are surprisingly modern and minimalist considering all of the different types of materials used in their creation!
