Buying jars one at a time gets expensive fast. This is a case of 24 matching 18oz (about 530ml) borosilicate jars with black ASTM D3475 push-and-turn lids and airtight gasket seals. Fill them, label them, put them on a shelf. The 5mm walls shrug off the kind of handling that chips thinner glass.
Why this one
Small-batch producers need containers that match each other. A case of 24 identical jars with certified CR lids, per-jar cost 40-50% under retail singles, solves the packaging problem in one order. Mason jars are cheaper but you would still be hunting for CR lids that fit.

Leave about half an inch of headspace when filling so the liner can compress against a clean rim. Then check your work: the lid should need a push and a turn, in that order, to come off.
Common questions
Are these lids truly child-resistant, or just a screw-cap?
Certified ASTM D3475. The push-and-turn mechanism needs two distinct motions to open, so it does not yield to a child's one-handed effort. The mechanism is the certification, not grip strength.
Can I put these jars in the dishwasher?
Glass yes, top rack. Hand-wash the lids, because repeated hot cycles degrade the gasket liner. Air-dry lids fully before reuse.
Will these work for hot-fill like jam or hot sauce?
The borosilicate handles heat (rated to 400F), the plastic lid does not. Let contents cool to room temperature, then seal.
Can I buy replacement lids separately?
Yes. CR lids in this size are available individually or in smaller packs, so a worn gasket does not retire the jar.
