Our Palm line of plates are made from the sheath of a palm tree, the part of the tree that is naturally shed as the tree grows. This sheath is then created into plates by hand. It is a renewable material that is light but extremely strong. The markings on the plates are totally natural, and give the plates a very eco-friendly look.
