Tefal Ingenio Preference On non-stick 4-piece cookware set with scratch-resistant Titanium 6x non-stick coating made of high-quality stainless steel is suitable for all types of stovetops, including induction. It is PFOA-free, dishwasher safe (except for the Ingenio handle), and easy to clean. The removable handle allows for stacking, and it is made in France. The cookware set features the Thermo-Signal technology, which glows dark red when the pan is optimally preheated and has reached the ideal frying temperature. Thanks to the Thermo-Fusion integral induction technology, the base of the pan heats quickly and evenly for optimal cooking results. Note: To extend the lifespan of the pan, we recommend hand washing with a non-abrasive sponge. When cleaning in the dishwasher, it is preferable to use gentle cleaning agents like liquid or gel. Ingenio handles and Ingenio cookware lids are not oven-safe. Included: 3 saucepans (16, 18, 20 cm), 1 removable Ingenio pot and pan handle.
