We're looking at roughly 30 to 45 days on that MOQ of 1,000 pieces, but we've got the 700ml and 1200ml sizes stocked pretty regularly if you need samples sooner, and the inner box plus outer carton packging is standdard.
That 400ml is surprisingly popular with home users for oilers — it basically fits most hands comfortably and teh narrow neck pours nicely — the 1000ml and 1200ml are what restaurants usually grab for soy sauce or vinegar sets.

borosilicate handles thermal shock better than soda-lime glass, so it'll survive the dishwasher and the microwave if someone forgets, but it's not ideal for direct flame or high-heat cooking surfaces (check lead time on custom logo etching if you need it, as that can add a week).

We've pretty much always got the 700ml and 1000ml in stock — the 400ml and 1200ml are usually made to order unless we have a production slot open — and that MOQ of 1,000 is per size, not mixed.
Custom designs are no issue if you send us the art within a week, and the color stays transparent, so the jar does what it does.
Our MOQ is 1000 pieces per model, but we can mix different capacities from 400ml to 1200ml in one order to hit that number.
Yes, samples are available. Just cover the shipping cost and we'll send one out, usually within 3-5 days.
We can share material test reports and thermal shock resistance data with your order. Certificates like FDA or LFGB are available for an added fee.
Each jar is packed in an inner box, then stacked in a sturdy outer carton with foam dividers. We've shipped thousands without issues.
Absolutely, we accept custom logos and designs. Just send us your artwork, and we'll handle the rest—OEM and ODM are both welcome.
