Our 4 oz black glass jars come in two finishes — black frosted and black UV — both built on a straight-sided 58-400 neck, so they're ready to pair with a wide range of closures. If you're formulating anything that reacts to light, this is the size and shade our wholesale buyers reach for most. Looking for a different size in the same finish?

Built for Light-Sensitive Formulas
Black glass isn't just a look. Both the frosted and UV finishes block light transmission, which matters if what's inside breaks down under sun or shelf lighting — think retinol serums, CBD salves, or botanical tinctures. Brands packaging anything photosensitive tend to go black or amber first and ask about capacity second.
A Size That Pulls Double Duty
4 oz sits in a sweet spot — big enough for a full-size body butter or hair pomade, small enough that it doesn't feel like overkill for a travel or sample line. We see it a lot in private label skincare, but it's also a common pick for spice blends, bath salts, and small-batch candle work where a wide mouth makes filling easier.
Why Glass Over Plastic
Glass doesn't leach into your product, doesn't hold onto old scent or residue between fills, and doesn't scratch up the way plastic does after a few trips through a fulfillment line. For anything oil-based or alcohol-based, that's not a small thing — plastic can degrade with certain formulas over time. Glass just doesn't have that problem.

Frequently Asked Questions
What finishes do the 4 oz black glass jars come in?
We carry two: black frosted, which has a soft matte texture, and black UV, which has a smoother, glossier surface. Both block light equally well — the difference is mostly look and feel.
Do these jars come with lids?
No, lids are sold separately so you can pick the closure that fits your brand — metal, plastic, dome, or flat. That also means you're not locked into one look. Browse compatible options in our caps and closures collection, or shop pre-paired options in our lidded jars collection.
Is there a minimum order?
Yes, these are sold wholesale by the case. Exact case counts are listed on each product page, and we're happy to talk through volume pricing if you're scaling up.
Are these jars food safe?
The glass itself is food-grade, but we'd recommend confirming compatibility for your specific formula and closure before running a full production batch — especially with anything acidic or oil-based.
Can I get custom labels or printing on these jars?
Yes. We offer custom label printing through our custom labels collection, and if you want something more permanent, our custom bottle printing service can etch or print directly onto the glass.
How fast does this ship?
Most orders leave the warehouse within 3-5 business days once placed, since we're shipping from US-based inventory. Want to check fit or finish before committing to a case? We offer sample orders too.
Why buy from The Bottle Depot?
