Black Corozo Button, "Five Squares" Flat Pillow 9/16" or 11/16"
Square button with four square holes. It's almost 1/8" thick but then slightly raised - 'pillowed' in the center, so it's not quite flat anymore. Silky finish, rich black corozo.
9/16" or 11/16"
Vegetable Ivory/Tagua/Corozo: Click here or here for wikipedia articles about this tropical palm tree nut. Tagua has been used for buttons since the 1880's, before plastic. It carves and dyes very well, is extremely durable, and looks better than plastic; not as shiny.
