Our quality placemats and coasters use a 5mm board topped with a unique and exclusive art print. Each is totally sealed with a high quality coating that is both stain and heat resistant to 212F. The placemats and coasters are then finished with a hard-wearing cork back that protects precious furniture. White and blue cornflowers, wild in a field, are depicted in Fleurs des Champs, from artist Silvia Vassileva.
