Natural coconut texture on this large navy scooped button. Real coconut, not plastic. Nice matte finish and the texture shows through the blue color. Edges are blue, too. Some natural variance in the coconut but fairly consistent. 2-1/4" diameter or slightly less.  Highest quality button about 3/16" thick. $5.50 each

The new ones came in less bright, a bit towards gray, in another listing for "Less Bright"
