LocknLock Airtight Food Storage Container - 3900ml

Yes, LocknLock food storage products are manufactured using BPA-free materials suitable for food contact.

No, the lid is not microwave-safe and should be removed before reheating food.

When the four clips are properly locked, the airtight silicone seal makes the container highly leak-proof for most liquids.

Yes, the material is designed to handle freezer temperatures safely.

The seal can be carefully removed with a dull tool or your fingers to rinse it, then reinserted into the groove.

Check that the silicone seal is properly seated in the lid groove and ensure the container is not overfilled, as excess pressure can prevent the clips from locking.

Use a rinse aid in your dishwasher or hand-dry immediately after the cycle ends to maintain the clarity of the plastic.
