Featuring a corrosion and scratch-resistant stone coating, this Salter Megastone Thermo Collar frying pan set is PFOA free and nine times tougher than standard non-stick, allowing you to prepare meals using little or no oil and use metal utensils without damaging the pans. Cook your meals to perfection thanks to the heat indicator technology on the collars, which change color once they reach the optimum cooking temperature. After cooking, simply hand wash the easy-clean pans for hassle-free cleanup.
