The bobo cover contains a Silicone gasket and it is normal for it to get stuck when it is locked. 2. It is recommended to use a Stainless Steel ring to avoid using tinplate rings that may rust and bite into the Silicone cover. 3. Stainless Steel is not rust-proof, but it is not easy to rust. In normal use, strong acids, alkalis, and salts should be avoided as much as possible to maintain the anti-rust properties of Stainless Steel.
