Each Solidteknics Nöni stainless steel pan is made from a single solid sheet of highly conductive 3mm non-nickel stainless steel. This creates a strong, seamless, low-maintenance cooking surface that cooks like iron but cleans like stainless steel. Free from toxins, heavy metals or synthetic coatings, it is durable enough to last for centuries, whether you use it in on a gas, induction or electric hob, in an oven, or outside on an open fire or grill.
