Brief history of an invention:
In 2008, by pure chance in Turin, Mattia Malavenda became aware of a material which, though apparently resembling ivory, was surprisingly the inside of a giant seed of a not well specified palm.
Through researches he discovered that ivory-like material come from a very unique plant that lives only in the Amazon rainforest of Ecuador, in South America.
It is called by the local people tagua or corozo, or more commonly vegetable ivory.
