Hello, scratches on enamel products can generally occur depending on the way they are used. The use of hard utensils such as metal spoons, forks, and knives, storing products nested together tightly, or leaving them empty for a long time at high temperatures can cause deformation on the surface. For the longer use of the product, it is recommended to prefer silicone, wooden or plastic kitchen utensils and to wash them by hand. With proper use, the enamel surface will maintain its stylish appearance for a long time.
