RefinementHouse Silicone Stretch Lids

Yes. While they are designed for round bowls and jars, the flexible silicone allows them to stretch over square or rectangular containers as well, provided the corners aren't too sharp to puncture the material.

They create a vacuum-tight seal that is excellent for keeping food fresh and preventing spills. For the best results, ensure both the rim of your container and the silicone lid are completely dry before applying.

Absolutely. Because they are made from food-grade, BPA-free silicone, they are perfectly safe to place directly over cut fruit and vegetables to keep them from drying out in the fridge.

Silicone can occasionally absorb strong odors, like garlic or onion. If you notice a lingering smell, a quick soak in a mixture of warm water and baking soda usually neutralizes it.

When microwaving, place the lid over the container but leave one corner slightly lifted to allow steam to escape. This prevents pressure buildup and ensures the lid doesn't pop off during heating.

They are top-rack dishwasher safe, which is the easiest way to clean them. If you prefer hand washing, warm soapy water and a standard sponge work perfectly.
