Temperature Tolerance: -20 °C–150 °C

Maintenance Instructions:

1. Before first use, it’s advisable to rinse the glass container. (The glass container is safe for the dishwasher)

2. The “Press Vacuum Seal Lid” should not be submerged or cleaned with water, but instead should be wiped with a moist cloth. (A vacuum valve exists in the lid; if water or powder gets in, it could block the valve and impair the vacuum functionality.)

3. To prolong the life of the sealed container, refrain from using abrasive cleaning tools such as steel wool on the glass container.

Guidelines for Use:

1. It is advisable not to store liquids or powders in the container. (When you empty it, water or powder might enter the vacuum valve and cause a blockage, affecting the vacuum efficiency.)

2. Ensure that the height of the contents in the container is at least 1 cm below the "sealed lid." For optimal vacuum sealing when pumping, press 20 times.

3. To enhance the shelf life of the stored items, press the air extraction valve on the sealed lid multiple times every 7–10 days to maintain optimal vacuum and lower oxygen levels inside the container.

4. Because of the nature of thermal expansion and contraction, storing hot food in the container will hinder achieving a good vacuum seal. Allow hot items to cool down to room temperature before sealing with the lid.

5. When in use, keep away from open flames and avoid strong impacts to prevent any distortion that could diminish the product's effectiveness.
