Our cooking utensils set are made from the highest quality materials. Food-grade silicone is safe to use for any type of food-it does not react with food or beverages, or produce any hazardous fumes. As such, they are longer-lasting than other kitchen utensil sets. This makes them very friendly when dealing with non-stick surfaces. The silicon heads cannot scratch or damage nonstick cooking pots, pans, and woks like wood or metals spoons do. Cooking with the non-stick silicone utensils set will protect your cookware from any scratches.
