This sparkling button top will look great on your next mosaic! It's 3/4" in diameter and feels nice & solid. Due to the snap button back, it DOES NOT lie flat. When using on a mosaic, please expect this to sit at a slight angle or use a thick putty-style adhesive that you can build up beneath it so it can lie flat.
Snap buttons are actually intended for use on a certain style bracelet with interchangeable decorative buttons, but we couldn't help but notice their potential for other types of artwork.
