These 12 acrylic buttons were made to resemble shell and they do look realistic. They are a creamy white color, 2-hole and measure 1-1/8". They have a slight well on top so the bottom is a little bit curved, not flat. The angle of the photo makes them look different sized, but they are all the same. There are 3 sets for sale individually. Any multiples will ship for the price of 1.
