Is there anything I should be particularly careful about when cleaning or storing the oval dome lid?

The thickness and finish of metal cookware directly relate to the safety of hands while washing dishes. The entire body of Ottinetti's oval dome lid is made of aluminum^[1]. Aluminum is convenient to handle because it is light, but it is a softer metal than stainless steel.

It is thin. In particular, because the rim portion is thin, it can easily bend and become dented if it receives an impact from being dropped on the floor or is pressed with strong force^[2]. In addition, because there are irregularities at the finished end of the rim, the edge is sharp^[3]. When washing, do not roughly sweep over the rim with your fingertips; instead, slowly wrap and wipe it with a soft sponge to avoid cutting your hands. When storing, you should place it separately on top so it is not pressed under heavy pots or frying pans to maintain its neat shape for a long time.
