Leak-Proof Mason Jar Lids & Sleeves Kit (for Wide Mouth Jars)

Yes, these lids are designed to fit any standard wide-mouth mason jar, regardless of the brand, as long as the jar has a 3-inch opening.

These lids are freezer-safe, making them ideal for long-term food storage. While the materials are microwave-safe, we recommend removing the lid before heating to prevent pressure buildup.

The silicone liners are dishwasher-safe and can be easily removed from the plastic lid using the integrated pull tab. We recommend washing them on the top rack for best results.

Yes, the platinum-cured silicone liner acts as a barrier between your food and the plastic lid. This ensures that only food-grade silicone comes into contact with your stored items.

Yes, the combination of the screw-top design and the silicone gasket creates an airtight, leak-proof seal. They are secure enough to transport liquids in a lunch bag without worrying about spills.

These lids are engineered with thicker, high-quality polypropylene plastic compared to standard metal or thin plastic caps. This construction prevents cracking and warping, allowing for repeated long-term use.
