The Leak-Proof Storage Lids by Ball are made from plastic and are airtight, dishwasher safe and freezer safe. These lids are not for use during canning. Use when freezing in mason jars or to provide a secure closure on an opened jar - they wont rust like the regular Ball rings do. Great for on-the-go salads and smoothies. The airtight seal makes them perfect for herbs and spices too.
These lids fit Ball mason jars. Select from either the regular mouth (65 cm opening outer diameter) or wide mouth (80 cm opening outer diameter) option depending on the mouth opening of your jars.
6 lids per pack.
Ridged edge providing a secure grip for getting on and off
