Better and better, day by dayThe SENIOR series is made of cast iron. Cast iron can withstand high temperatures, retains heat well and spreads it evenly. The enamelling on both the inside and outside makes these pans hardwearing and easy to keep clean. Because cast iron is heavy, you need a good grip when lifting. That's why we put two handles on the pans, so you can lift them with both hands. Works well on all types of hobs - and the casseroles are also oven-safe.
