Orblue Silicone Stretch Lids

While the lids are round, the flexible silicone material allows them to stretch over square or rectangular containers, provided the perimeter isn't too large. However, they are designed primarily for round bowls, cups, and jars to ensure the most secure, airtight seal.

Yes, they are microwave-safe. You can leave them on your containers while reheating food, but ensure you leave a small gap or vent to allow steam to escape.

For the best results, make sure both the lid and the rim of your container are completely dry before applying. Stretch the lid starting from one side and pull it across to the other, pressing down on the edges to create a vacuum seal.

Yes, they are dishwasher safe. You can place them on the top rack for easy cleaning, or simply wash them by hand with warm, soapy water.

The set includes six different sizes to accommodate various openings. While they are highly stretchable, they are best suited for standard kitchen bowls, cups, and jars rather than extra-large mixing bowls or oversized platters.

Because they are made from high-quality, non-porous food-grade silicone, they generally do not absorb odors. If you store something particularly pungent, a thorough wash with hot, soapy water or a run through the dishwasher should remove any lingering smells.
