The jars can’t go in the freezer for the most part.
There are glass storage containers similar to Tupperware that can though. But longevity is a matter of the lids.
At larger than a quart the jars also represent a food safety issue. Tall narrow containers won’t cool as fast as flat wide ones, often leaving the food in the danger zone too long. Health codes in most states require restaurants to use wide flat containers for anything larger than a quart.
So the jars are mostly a good solution for smaller amounts of food that are fridge bound. Not large amounts or anything you’ll freeze.
