1. When removing a container from the freezer, do not open it immediately; it is best to let it sit at room temperature for 1–2 minutes before opening.

2. When using the container in a microwave, foods with high oil or sugar content can cause the container to deform due to rapid temperature increases. Therefore, it is best to use containers specifically designed for microwave use when heating such foods.

3. Carbonated beverages (soda, cola, etc.) can compromise the container's seal. Similarly, foods that foam, fermented foods, or hot foods can reduce sealing performance; please avoid storing these types of items in the container.

4. Storage times vary depending on the food; do not rely solely on the container's sealing capabilities-it is best to consume the food as soon as possible.
