These burner covers are for decorative purposes only, and should be removed when stove and oven are in use. This will protect and preserve the laminate which has been carefully cut and adhered to the metal cover. You will receive a standard set of four, 2 small and 2 large. We have carefully cut and adhered the laminate in a scalloped pattern similiar to Pioneer Woman melamine dishes. In the event of a splash or spill, simply clean with a damp cloth, the laminate is quite durable and cleans nicely. Also available in Flea Market Floral pattern, which is currently in a separate listing. Good luck if you decide to bid.
