21-piece non-stick aluminum cookware set, labeled "H.N.". This set includes various pots, pans, and utensils, suitable for a range of cooking tasks. The cookware appears to have a light-colored, possibly granite or ceramic-based non-stick coating, which is designed to prevent food from sticking and facilitate easy cleaning. Non-stick cookware often uses materials like polytetrafluoroethylene (PTFE), commonly known as Teflon, or ceramic coatings. When buying non-stick cookware, it's important to consider factors like material, weight, maintenance, coating, and temperature resistance.
