Beautiful velvet matte finish, dark indigo/almost black, high quality 2-hole button. 3/4" and almost 1/16" thick. 20mm.  ust enough of the shell's natural glow comes through to create slight iridescence and some variance. They have a gorgeous lustre that is almost like suede.  (Clearly these are not plastic buttons!)  Smooth but not shiny. For your best uses. The backs are mottled black shell.  

$1.40 each.  

We have the matching button in 5/8" and 1-1/8" sizes, too.
