【After Use】

• Wash thoroughly with dish detergent to remove dirt, then wipe away moisture and dry completely.

Handling Precautions

• When food is hot, let it cool before closing the lid. Temperature differences can make the lid difficult to open.
• For regular care, wash with a sponge and detergent. (Avoid using steel wool or abrasive powders as they will scratch the surface.)
• Avoid using or storing highly acidic foods as they may cause corrosion.
• Do not use when filled to the brim with water or other liquids.
• Do not store food for extended periods.
• Do not damage the packing or the mouth of the main body. (This will reduce airtightness.)
• This is not completely airtight, so liquids may leak when containing foods with high moisture content.
• When washing the packing, do not stretch it while cleaning. (The packing may stretch and become impossible to set properly.)
• Clean the packing regularly. It can also be sterilized by boiling. (It may temporarily compress but will return to its original shape after being left alone.) Set it correctly after washing.
• After washing, do not close the lid immediately - allow to dry thoroughly.
• Do not use in microwaves.
• After use, remove aluminum foil cases and similar items rather than leaving them inside, as they may cause discoloration or rust.
