Premium Stainless Steel: Godmorn's espresso maker is made of food-grade safe stainless steel which is corrosion-resistant, rust-resistance and easy to clean. Safety Valve & Leak-Proof: The water level should be lower than the safety valve when filling the lower pot; ensure rubber gasket is fitted and tighten the pot; avoid using the handle to tighten, if loose, secure it with a screwdriver from the bottom.
