Duebest Silicone Stretch Lids

Yes, the flexible silicone material is designed to stretch over various shapes, including square and rectangular containers, provided the container's perimeter fits within the stretchable range of the lid.

These silicone lids are freezer-safe, making them excellent for storing leftovers. While they are heat-resistant, we recommend checking the specific temperature limits if you plan to use them in the microwave, and always ensure they are not sealed airtight when heating to allow steam to escape.

For the best seal, ensure both the rim of your container and the silicone lid are clean and dry before applying. Start by placing the lid on one side of the container and stretching it across to the other side, smoothing out the edges to remove any air pockets.

Yes, they are dishwasher safe. We recommend placing them on the top rack to maintain their shape and longevity.

The set includes six lids ranging from 2.5 inches to 8.25 inches in diameter, allowing you to cover everything from small condiment jars to large mixing bowls.

High-quality food-grade silicone is non-porous and generally does not absorb odors or transfer flavors to your food. If you notice a lingering scent after storing strong-smelling items like onions or garlic, a thorough wash with warm, soapy water or a vinegar soak usually resolves it.
