Compatible Closures for 0.5 oz Bottles
These bottles pair with a full range of closures sold separately. Choose from bottle lids, dropper caps, and fine mist sprayers — all stocked to match the 18-400 neck finish. For a pre-assembled set with closure included, visit our retail collection.
Serum, Tincture & Essential Oil Packaging
The 15ml capacity is a standard format in skincare, aromatherapy, and herbal supplement production. Amber and black UV versions block light to protect photosensitive formulations — important for CBD tinctures, essential oils, and botanical extracts. Clear and frosted versions work well where product visibility or premium aesthetics matter. All variants use Type-III soda-lime glass: BPA-free, chemically inert, and non-reactive with most liquid formulations.
Sample Kits & Travel-Size Retail Products
Half-ounce bottles are a go-to format for brand sampling programs and travel-size retail. At 15ml, they're the right size for skincare trial kits, perfume samples, roller bottle refills, and single-use aromatherapy sets. Buying wholesale keeps unit cost low enough to include samples with every order — or build a full sampler product. Pair with our sample collections or custom labels to create a finished, branded kit.
Why Glass for Small-Format Packaging
At 0.5 oz, glass has a real advantage over plastic: it doesn't absorb fragrance, doesn't off-gas into the product, and holds up against concentrated actives that degrade plastic over time. It's also 100% recyclable — which matters to the customers buying your finished products. For premium serums, high-concentration essential oils, or regulated tinctures, glass is the material the market expects.

Frequently Asked Questions
What is 0.5 oz in milliliters?
0.5 oz is equal to approximately 15ml. These bottles have a 15ml capacity, which is the standard size for skincare serums, essential oil singles, and tincture samples. It's also commonly referred to as a half-ounce or 1/2 oz bottle.
What neck finish do these bottles use?
These 0.5 oz glass bottles use an 18-400 neck finish. The "18" refers to the outer diameter of the neck in millimeters, and "400" refers to the thread style.

Do the bottles come with lids or droppers?
Closures are sold separately in our caps and closures collection. This gives you the flexibility to choose the right closure type for your product — dropper, spray, or screw cap. If you want bottles with closures already included, see our retail pre-assembled sets.
What colors are available?
0.5 oz glass bottles are available in 8 finishes: clear, amber, amber frosted, clear frosted, black frosted, black UV, blue, and green. Amber and black UV provide UV protection for light-sensitive products. Frosted finishes give a premium matte look popular in skincare and fragrance packaging.
