Tagua nuts are the seeds from the fruits of the Ivory Palm. Female palms have clusters of large, woody, pointed, brown fruits that are the size of grapefruits or melons. The seeds are harvested from fruits that have naturally fallen to the ground. The Tagua nuts & the dyes with which they're colored are eco-friendly & provide a self-sustaining source of income for families in South America.
