Our 4 oz glass bottles are built for businesses that need dependable packaging in bulk — not just a handful of colors, but eight finishes across amber, clear, black, blue, and green, each one food-safe and rated for wholesale volume. Whether you're filling essential oils, tinctures, serums, or aromatherapy blends, this size covers a range of products businesses package every day. We've shipped these bottles to over 5,000 customers since 2018, and every order ships from the US in 3-5 days with a satisfaction guarantee behind it.
Available in amber, clear, black, blue, and green, plus frosted options in several of those shades — these bottles work whether you're bottling a single small-batch product or filling a private label order.
4 oz Glass Bottles for Sprayers
Pair these bottles with fine mist sprayers or a simple closure (both sold separately) and you've got a toner, facial mist, or room spray ready to fill. Amber and black finishes add UV protection for formulas that break down in light — think vitamin C serums or botanical extracts — while clear and frosted glass let the product itself do the selling on a retail shelf. Already need the sprayer attached? Our 4 oz glass spray bottles come ready to fill.
4 Ounce Bottles for Droppers
The Boston round shape on these 4 oz glass bottles is the same style tincture and essential oil brands have used for decades, and there's a reason it stuck: a narrow shoulder that keeps a dropper or orifice reducer steady, and a base wide enough to sit flat on a counter or shelf. Pair with a glass dropper (sold separately) for tinctures, serums, and essential oil blends, or skip a step with our 4 oz dropper bottles, which come with the dropper already fitted.
Why Glass
Glass doesn't react with what's inside it. No leaching, no flavor transfer, no breakdown from essential oils or high-proof tinctures the way some plastics experience over time — and unlike plastic, glass doesn't absorb odor from a strong formula after repeated refills, so the next batch tastes and smells like it should. It's also fully recyclable, which matters to a growing share of the customers your brand is trying to reach. And on a practical level, glass simply reads as more premium on a shelf. Customers pay more for products in glass than the identical formula in plastic, even when they can't articulate why — the weight of the bottle in your hand does some of the selling for you.
Choosing the Right Finish
Amber and black block the most light, which is why they're the standard choice for anything photosensitive — retinol serums, CBD and hemp extracts, and certain essential oil blends that degrade fast under UV exposure. Blue and green land in the middle: some light protection, plus a color story that works well next to a eucalyptus, tea tree, or mineral-based product line. Clear puts the product itself on display, which matters when the liquid is part of the pitch, like a golden facial oil or a visibly pure toner. Frosted versions of amber, black, and clear soften the look of the glass without losing the base color's protective qualities, and they tend to photograph well for product shots and social content.

FAQ
What sizes and colors are available?
These bottles are 4 oz, and come in amber, clear, black, blue, green, amber frosted, black frosted, black UV, and clear frosted finishes. If you need a different size, we carry the same Boston round shape from 0.5 oz up to 32 oz.
Do these bottles come with a lid or cap?
Not by default — glass and closures are sold separately so you can mix and match sprayers, droppers, or standard caps depending on the product. If you'd rather have the lid included from the start, our 4 oz glass bottles with lids come as a complete set.
Is there a minimum order?
These are sold by the case for wholesale pricing, and case sizes vary by color and finish. If you only need a smaller quantity to test a formula or run a sample batch, check our samples collection before committing to a full case. Reach out if you're not sure what quantity works for your order — we can help you figure out the right case count for a first run or a reorder.
Are these bottles food safe?
Glass itself is inert and safe for food and cosmetic use — it's one of the main reasons brands move to glass in the first place. That said, always confirm the specific closure and any coating or lining you pair with the bottle is rated for your product before you go into production.
Can I add custom labels?
Yes. We offer custom bottle labels sized to fit these bottles, so you can move from blank glass to a finished retail product without sourcing packaging from multiple vendors.
Can you print directly on the bottle?
For brands that want a more permanent look than a label, we also offer custom bottle printing. It's a separate process from labeling, and it works well for larger runs where you want branding baked into the glass itself.
How fast do orders ship?
Orders ship from our US warehouse in 3-5 business days. We've been supplying wholesale glass packaging since 2018 to more than 5,000 customers, and every order is backed by our satisfaction guarantee.
