These buttons are made from the corozo nut, or tagua nut. This is the seed of extracted from the fruit of a tropical palm. Because corozo is a natural product, it shows a natural pattern, and this gives it its unique distinction. Corozo buttons are also relatively scratch resistant and resist fading. The dyes used with corozo are non-toxic and biodegradable. The entire process from plant to product is environmentally friendly as the fruits are only picked once fallen naturally.
