Reusable Silicone Stretch Lids Set

While the lids are designed with a round shape, the flexible silicone material can stretch over square or rectangular containers, provided the corners are rounded. However, for the most secure, airtight seal, they are best suited for round bowls, jars, and produce.

Yes, when applied correctly to a dry, smooth-rimmed container, these lids create a reliable airtight seal. While they are excellent for preventing spills in the fridge or freezer, they are not intended to be completely watertight if a container is turned upside down or shaken vigorously.

For the best grip, ensure both the rim of your container and the underside of the silicone lid are clean and dry before applying. If the surface is wet or greasy, the silicone may slip; simply wiping the rim with a cloth usually solves the issue.

Yes, they are microwave-safe. Just be sure to leave a small gap or vent the lid slightly to allow steam to escape while heating, which prevents pressure buildup.

Silicone is generally non-porous, but it can occasionally absorb strong odors over time. If you notice a lingering scent, soaking the lids in a mixture of baking soda and warm water or running them through a dishwasher cycle usually neutralizes the smell.
