If you use Mason jars for drinking or storage, it is essential to have an adequate supply of one piece lids. Two piece lids seal equally well but they are cumbersome to repeatedly take on and off the jar.
These serve a similar function to the plastic Ball storage lids but are more durable, seal better, and look nicer. The plastic ones tend to crack and break, especially if the jar gets dropped or tipped over.
They are made of tin plated steel with a BPA Free plastisol liner.
We use them a lot for capping unfinished drinks, leftover food, fermented food, and sauces in the fridge. Our kids drink out of half pint jars, so when they don’t finish their drink we just put a lid on it and put it back in the fridge. In the pantry we use them on nuts and seeds, flour, sugar, and other staples.
Fits all regular mouth Mason jars.
Hand wash and dry to avoid rust (we put them in the dishwasher and deal with a little rust).
