Made of natural shell and beautifully carved on one side, this lovely button has two sides so opposite from each other you almost have two buttons in one. On one side is creamy pink and blue shell carved with an intricate scrolling design and the other is mottled brown like the ocean floor. Because they are made of organic material, each button is different, so expect variations. Shank hole measures 2mm. Button diameter is about the size of a quarter.
