11/16" diameter, dimensional button with a tiny flower in the center. Including the large loop shank (whose opening is 3mm), it's a bit more than 1/4" deep.  It has a matte finish; barely any shine. USA Made of Pewter. These pewter buttons have a substantial, thick, warm, rustic heirloom look and feel, and are a bit heavier than most of our metal buttons, with a nice 'roundedness'.  $3.75 each.
