This pack of 156 contains clean, empty 15 ml amber glass bottles supplied without caps. 15 ml is one of the most sought-after sizes in this category: larger than 10 ml but still comfortable to hold, making it a strong choice for essential oil blends, facial serums and tinctures alike. You can choose the closure to fit your intended use.
What is in the pack of 156
156 clean, empty 15 ml amber glass bottles. Height approximately 65 mm, diameter 28 mm, neck thread GL18. An empty bottle weighs around 30 g and gross pack weight is approximately 5.15 kg. Country of origin: China. The bottles are clean inside and out, but a warm-water rinse before filling is recommended.
Amber glass and UV protection
Amber glass blocks UV radiation and the shorter wavelengths of visible light. These wavelengths most rapidly trigger oxidation in essential oils and botanical extracts. Stored in amber glass, preparations retain their scent profile and active ingredient content for considerably longer. Glass is inert and does not migrate plasticisers or other substances.
Why no cap
The no-cap format provides flexibility. The same bottle accepts an aluminium screw cap, a black pipette dropper, a childproof closure or a tamper-evident dropper cap. Each recipe can be paired with the ideal closure, and there is no need to commit in advance to a fixed cap stock.
Areas of use
- Bottling essential oil blends in the most common 15 ml size
- Dispensing facial serums and moisturising oils
- Filling tinctures, hydrosols and flower essences
- Custom perfume bases
- Consistent packaging for own-brand cosmetics
Cleaning and reuse
Before filling, wash the bottles in warm soapy water, rinse and dry. For stronger scent residues, use food-grade alcohol. Avoid the dishwasher to protect labels and printed markings. Glass is recyclable many times over, so the bottles can return with new fills in further seasons.
