Hand printed in the USA on genuine Italian Botticino marble, these coasters are available in a vast array of themes and styles that include everything from low-brow whimsy to fine art. They come with high-quality cork backings to protect your furniture. Please keep in mind that the marble is tumbled to create irregular edges and minor chips and cracks which give the finished product a sense of age and authenticity. These random imperfections add character and interest and are not considered to be defects.
