Our 4 oz glass bottles with lids arrive ready to fill. Each one is a classic Boston round with a black screw cap already matched to it, packed 12 to a box. No hunting for the right closure. No guessing about neck sizes. Every bottle holds 4 fl oz (about 120 ml) and uses a 22-400 neck finish, and every cap is black PP with a polycone liner that presses into the bottle's lip for a tight, leak-resistant seal. If you sell tinctures, extracts, beard oil or small-batch hot sauce, this is the size your customers already expect to see.
The collection comes in multiple color finishes, from clear and frosted glass to darker UV-blocking tones. Want a specific shade? Our 4 oz amber glass bottles with lids have their own page. Need a different size in the same style? Step down to 2 oz glass bottles with lids for trial sizes, or up to 8 oz glass bottles with lids for full-size refills.
4 oz Bottles with Lids for Tinctures, Extracts and Oils
Four ounces is the workhorse size for liquid products. Big enough to feel like real value on a shelf. Small enough to ship cheaply and sell at a price people don't think twice about. Herbalists fill it with tinctures and glycerites. Home cooks and small food brands use it for vanilla extract, bitters, simple syrup and chili oil. Beard and hair care brands put their oils in it because it fits a shaving kit without hogging space.
The liner is the part most people overlook, and it's the part that matters most for thin liquids. A flat liner just sits against the rim. A polycone liner is shaped like a shallow cone, so as you tighten the cap it wedges into the bottle opening and seals around the inside edge. That's why it holds up with liquids that like to creep, like essential oil blends and alcohol-based tinctures. Lay a filled bottle on its side in a shipping box and it stays put.
A few filling habits get the most out of that seal. Leave a little headspace below the neck, especially with alcohol tinctures that expand in warm trucks. Wipe the threads dry before capping, because a film of oil on the rim is the most common reason a cap backs off. Then tighten firmly by hand until the liner compresses. You'll feel it stop. If you're batching dozens of bottles at once, a cheap funnel set and a lint-free cloth will save you more time than any piece of equipment. And if you plan to sell online, test one filled bottle in your actual shipping box before you launch. Ten minutes of testing beats a week of refund emails.
Need to dispense drop by drop instead? The bottles take any standard 22-400 closure, so you can switch to a glass dropper later without changing bottles, or start with our ready-made 4 oz glass dropper bottles.
Glass Bottles with Caps for Skincare and Hair Care
Beauty brands like the 4 oz Boston round for toners, facial oils, hair serums and body oils. The narrow neck controls the pour. The rounded shoulder looks clean with a simple wraparound label. And glass reads premium in a way plastic rarely does at this price. Frosted finishes soften the look for spa and wellness lines, while darker glass helps protect light-sensitive formulas like vitamin C blends and botanical oils that fade under store lighting.
Planning a mist instead of a pour? The same bottle shape comes fitted with fine mist sprayers in our 4 oz glass spray bottles collection, which works well for room sprays, linen mists and facial mists.
Why Glass Beats Plastic at 4 oz
Glass is chemically inert. It won't absorb scent, react with essential oils or stain from turmeric, coffee or chili the way many plastics can. What you bottle on day one smells and tastes the same on day ninety. It's also easy to sanitize, fully recyclable and reusable, which matters to customers who care where their packaging ends up.
Then there's the hand feel. A filled 4 oz glass bottle has real weight to it, and people notice. That weight quietly tells a buyer your product is worth what you're charging.
Color is a practical choice, not just a style one. Clear glass shows off your product, which is ideal for colorful syrups or infused oils. Amber and other dark glass block much of the UV light that breaks down oils, extracts and herbal remedies. Frosted glass diffuses light and gives you a softer, matte look without hiding the fill level completely. Match the glass to what's inside and you'll get better shelf life and a better-looking product.

4 oz Glass Bottles with Lids: FAQ
What sizes and colors are available?
Every bottle in this collection holds 4 fl oz (about 120 ml). They come in multiple color finishes, including clear, frosted and darker UV-protective glass. For other capacities, check out our 2 oz and 8 oz glass bottles with lids.
What lid comes with the bottles?
Each bottle includes a black PP screw cap with a polycone liner, sized for the 22-400 neck finish. The cone-shaped liner seals against the inside of the bottle opening, so you get a tight closure without any extra inserts or shrink bands.
Can I use a different closure?
Yes. Any 22-400 closure fits, including droppers, sprayers and treatment pumps. Browse our full range of caps and closures, or pick up spare black bottle caps to keep on hand. If you'd rather buy bottles and closures separately, start with our 4 oz glass bottles without caps or the full range of glass bottles in every size.
Is there a minimum order?
The smallest order is a single 12-pack, so you can test a new product without overbuying. Ordering a few styles at once? Build your own bundle to mix and match. Not sure which finish suits your brand? Order sample bottles first.
Are these bottles food safe?
Glass is one of the most common materials for food and beverage packaging because it's non-porous and doesn't react with what's inside. That said, always verify compatibility for your specific application, especially for acidic recipes, high-proof alcohol or anything you plan to heat.
Can I add my own label or branding?
Absolutely. The smooth, rounded body of a Boston round takes a wraparound label well. We offer custom bottle labels printed to fit, so your bottles arrive shelf-ready.
How fast will my order ship?
Orders ship anywhere in the USA and typically arrive in 3–5 business days. That makes it easy to restock quickly when a product takes off.
More than 5,000 businesses and makers have trusted The Bottle Depot since 2018, and every order is backed by our satisfaction guarantee. Looking for other ready-to-use packaging like pump, dropper or roller bottles? Explore our full retail collection.
