Sturdy glassware with glass lids. The generic seals are easily replacable, and will be available for decades to come. They can be put in the microwave or freezer (without the seal), and obviously don’t leech any microplastics or hormones into your food.
Produced in Germany since 1900.
Traditionally these are used for making jam, but the larger ones also make for good storage containers for cereal, pasta, flour and sugar etc
Always preferred Mason/Ball to Weck because the Weck rubber rims can be finicky and little metal clips tend to go missing.
The one Weck container I have the rubber rim went bad pretty quickly on and the replacement doesn’t fit quite right so it leaks if you shake it at all.
I’m gonna also side on the twist on 2 piece lid designs are better.
The Ball two-piece-lid is pretty rad.
Had that problem too. And the glass chipped easily imo.
