Cobalt Blue Glass Jars

About

Our cobalt blue glass jars are built for brands that need real UV protection without sacrificing shelf appeal. Available in 0.5, 1, 1.7, 2, and 4 oz sizes, these glass jars work as straight-sided and cylinder low-profile styles, so whether you're packaging a thick balm or a pourable oil, there's a shape that fits. Jar lids are sold separately, which means you're not locked into one closure — pair these jars with plastic , aluminum , or bamboo lids depending on the look you're after. Want the closure already sorted for you? Check out blue glass jars with lids instead.

A 1 oz jar fits a standard 30ml cream fill, and the 4 oz size covers a full body butter without needing a second container size.

Pharmacies and herbal product makers lean on cobalt blue glass for exactly this reason — it's a packaging choice that does real work, not just a style statement. If your formulation is light-sensitive by nature, this is one of the more straightforward ways to extend shelf life without reformulating anything. Why Glass Glass doesn't leach, doesn't absorb odors from previous contents, and doesn't react with essential oils or acidic formulas the way some plastics can over time. It's also fully recyclable, which matters if your customers care about what happens to the container after the product's gone. None of that changes with color — cobalt blue gets you all of that plus the added UV filte
