Operating Instructions
Sealing the Container
- Fill: Place food or items into the container. Do not overfill; leave some space for the lid.
- Position Lid: Align the lid with the container, ensuring the silicone gasket is properly seated.
- Lock Tabs: Press down firmly on each of the four locking tabs until they click into place. This creates the airtight and leak-proof seal.

Opening the Container
- Release Tabs: Gently lift each of the four locking tabs outwards until they disengage from the container base.
- Remove Lid: Lift the lid off the container.
Microwave Use
- When microwaving, always unlatch all four locking tabs and slightly open the lid to allow steam to escape. This prevents pressure buildup.
- Do not use the container in a conventional oven, under a grill, or on a stovetop.
- Avoid heating oily or sugary foods for extended periods, as they can reach very high temperatures and potentially damage the container.
Freezer Use
- Containers are safe for freezer storage.
- Allow hot foods to cool before placing them in the freezer to prevent thermal shock and potential damage to the container or food.
Maintenance and Care
Cleaning
- Dishwasher Safe: Containers and lids are safe for the top rack of a dishwasher.
- Hand Washing: For best results and to prolong the life of the silicone gasket, hand washing with warm, soapy water is recommended.
- Stain Removal: For stubborn stains, a baking soda paste can be used. Apply the paste, let it sit for a few hours, then wash and rinse.
- Odor Removal: To remove odors, wash thoroughly and air dry with the lid open. Placing a crumpled newspaper inside for a day can also help absorb odors.
- Gasket Care: The silicone gasket can be removed for thorough cleaning if necessary. Ensure it is properly re-inserted before sealing.
