Weck Med Keep Fresh Lid
These BPA-free plastic lids will expand to prevent pressure building inside Weck glass jars when used for freezing. As these lids provide a strong seal and will not react with foods or absorb odors, we recommend them particularly for refrigerator and freezer storage. Microwavable and dishwasher safe.
