This eye-catching button is a mixed media creation, including silk screens, textures and metallic pigment powders.  It's 2 1/8" in diameter.
It's best not to wash this button, but if you must, wash it by hand and line dry it.  Don't dry clean it.
The shank on the back is guaranteed not to fall off, but I've provided instructions if you would like to remove the shank for jewelry making.
