For the matching Placemats and Coasters type codes 21818 & 21816 The quality of each Pimpernel tablemat and coaster is outstanding, using a 5mm board which is topped with a unique artistic print design, then sealed with a high quality lacquer finish. This lacquer finish protects the mats from staining and is also heat resistant to 100 degrees centigrade. The whole placemat is then finished with a hard wearing cork backing to protect against scratching furniture surfaces.
