The 4 oz amber glass bottle is a go-to size for brands packaging anything that shouldn't sit in direct light. Every bottle here is a classic Boston round shape with a 22-400 neck finish, available in true amber or a frosted amber finish for a softer, matte look. Need a different capacity? The full amber glass bottles collection runs from 0.5 oz up to 32 oz.
Built for Light-Sensitive Formulas
Amber glass blocks out UV rays that break down oils, extracts, and active ingredients over time. That's why it's the standard choice for essential oils, tinctures, serums, and anything with a shelf life you actually want to protect. A 4 oz bottle is also the right size for a lot of formulas — big enough to feel like a real product, small enough that customers won't feel like they're overpaying for empty space. If you're working with a different neck finish or bottle shape, our Boston round and specialty bottle catalog covers the rest of the lineup.
A Reliable Choice for Small-Batch and Private Label Producers
Whether you're bottling your first batch or scaling up an existing line, the 4 oz size hits a sweet spot for testing new SKUs without committing to a huge minimum order. It's also a popular sample and travel size for brands that sell a larger container as their main product. The 22-400 finish is compatible with droppers, pumps, sprayers, and standard caps, so switching closures later doesn't mean switching bottles.
Why Glass
Glass doesn't leach chemicals into your product, doesn't hold onto odors between fills, and doesn't degrade under UV exposure the way some plastics do. It's also fully recyclable, which matters more and more to the customers buying what you make. We supply bottles only — caps and closures are sold separately, so you can pick exactly the finish and function your product needs instead of getting stuck with whatever came in the box.

FAQ
What sizes and colors does the 4 oz amber glass bottle come in?
This collection covers the 4 oz Boston round in true amber and frosted amber. Both use a 22-400 neck finish, so closures are interchangeable between them.
Do the bottles come with lids or caps?
No — bottles and closures are sold separately so you can choose exactly what fits your product, whether that's a dropper, pump, sprayer, or standard cap. Browse caps and closures to find a match, or shop our pre-capped retail bottles if you'd rather skip that step entirely.
Is this glass food safe?
Yes, our glass bottles are food-grade. That said, always verify compatibility with your specific formula before running full production, especially for anything with a low pH or high alcohol content.
Is there a minimum order?
Bottles are sold by the case, so your minimum is one case — no separate small-order fees. Not sure this is the right fit yet? Order a sample before committing to a full case.
Can I get custom labels for these bottles?
Yes. We offer custom bottle labels sized to fit the 4 oz Boston round shape, so your branding looks intentional instead of stretched or cropped.
