There's a Classico pasta sauce line that uses jars molded with Atlas Mason on them and fit Mason jar lids but are not designed to be reused for canning. Just for marketing.
As an added bonus they seem to be far more durable than our regular glasses and tumblers; we end up breaking one of those every couple of months. They have been almost completely replaced by "free" pasta jars at this point and we have yet to break any of those.
