Feminist coasters! Each tile includes four felt tip backers to prevent scratching against furniture or other surfaces. Due to the handmade nature of our art, all images will have a distressed look (where the underlying coaster shows through the image), with slight variations on the amount and location of distressing. Characteristics of the natural stone used for our coasters include variances in shade, color and marble pattern. The edges and backs of the tiles are roughed and antiqued.
