2. Can I fill my food jar/ bottle with Chinese herbal soups/ coffee/ milk etc?

3. Why does the food jar's lid set sometimes difficult to open?

The lid may become difficult to open from the inner pressure caused by filling with hot food. In this case, remove the lid cover and push a small, rounded object such as the back of a toothpick (please avoid any sharp object) into the hole in the center to release the pressure, taking care not to tear the valve packing. (Please refer to the illustration in products' instruction manual).

  3. Foods and beverages high in salt: Although the liner is made of 18/8 stainless steel, salf from foods such as miso soup, other soups and sports drinks may cause rust resulting in loss of thermal insulation.
