Product description

Dropper black-gold, 56 mm

The dropper seals a bottle with an 18/410 neck and precisely dispenses the contents drop by drop. It is suitable wherever only a few drops are applied – for facial serums, oil blends, tinctures, concentrates with active ingredients, and hair or nail oils. The black-gold finish gives the bottle a darker, more understated look and pairs well with amber, black, or frosted glass.

The dropper consists of a glass tube, a soft silicone bulb, an aluminium collar, and an internal plastic thread. Glass and silicone are compatible with oils and common cosmetic raw materials. The packaging is intended for use with cosmetic products; the declaration of conformity is available with the product.


What the dropper is suitable for

  • Precise dispensing – the silicone bulb draws up a small amount and releases it drop by drop, which is convenient for serums and concentrates.
  • More hygienic use – the contents are not scooped out with fingers from the bottle neck but applied directly from the dropper, so fewer contaminants enter the product.
  • Oil and alcohol-based contents – glass and silicone are suitable for oils, oil extracts, and tinctures, with which plastic dispensers may soften over time.
  • Cohesive appearance – the black-gold collar looks uniform on dark glass and complements black or gold labels.

Use and bottle selection

The dropper screws onto a bottle with an 18/410 neck. However, the length of the glass tube also matters: it should reach almost to the bottom of the bottle so that the remaining contents can be drawn up, but it must not be longer than the internal height of the bottle, otherwise it would rest against the bottom when tightened. The tube length is listed in the product specifications; we recommend comparing it with the height of your chosen bottle. Bottles with the same neck type and ready-made bottle + dropper combinations are available in the Handymade range. For custom combinations, we recommend testing the seal, dispensing, and compatibility of the packaging with your specific formulation.

Fill the bottle only to the nominal volume, not to the brim. The difference between the nominal and total volume is the allowance for the glass tube, which displaces some of the contents upwards when screwed in. If overfilled, the contents will be pushed out through the thread when closing.

The dropper works best with liquid and slightly viscous contents – oils, serums, tinctures, concentrates. Thick gels and creams are drawn up through the tube slowly and unevenly; a pump or jar is more suitable for those. With very thin, watery contents the drops flow more quickly and exact quantities are harder to measure.


Good to know

  • Before first filling – disassemble the dropper into the collar and glass tube, wash with warm water, disinfect with isopropyl alcohol or ethanol, and allow to dry completely. Moisture in the tube could dilute an anhydrous product or promote microbial growth.
  • Do not leave contents in the bulb – after drawing up the product, always squeeze it back into the bottle. The silicone bulb is not designed for prolonged contact with contents, and residues inside are harder to clean.
  • Transport and carrying – the dropper seals under normal use. For shipping or travel, test the behaviour of your specific bottle + dropper combination with the given contents, or seal the bottle with a full cap for transport.
  • Glass fragility – the glass tube may break if dropped. Handle it carefully when cleaning and do not over-tighten the collar.
  • Reuse – after thorough cleaning and disinfection the dropper can be used again. If the silicone bulb loses elasticity or changes colour, replace it.
  • Recycling – the dropper is made of several materials (glass, aluminium, plastic, silicone), so where possible disassemble it into individual components before disposal.

Concentrated essential oils and alcohol-based contents may stain or soften the plastic thread and affect the elasticity of the silicone bulb with prolonged contact. With such blends, inspect the dropper after a period of use and replace it if necessary.


Frequently asked questions

Which bottles does the black-gold dropper 56 mm fit?
The dropper fits bottles with an 18/410 neck. In addition to the neck type, check the length of the glass tube against the height of the bottle – the tube should reach almost to the bottom but must not rest against it. Ready-made bottle + dropper combinations are listed separately in the range.
Is the dropper suitable for essential oils and oil serums?
Yes, the dropper is suitable for oil-based contents including blends with essential oils. The tube is glass and the bulb is silicone; both materials are compatible with oils. With highly concentrated essential oils, check the plastic thread and silicone bulb after extended use for any change in colour or elasticity.
Can the dropper be washed and reused?
Yes, the dropper can be reused after cleaning. Disassemble it, wash with warm water and dish soap, rinse, disinfect with isopropyl alcohol or ethanol, and allow to dry completely. We recommend this procedure before filling a new product each time, especially when switching from an oil-based to a water-based product.
Why does the contents get pushed out when I screw the dropper on?
The bottle is likely filled to the brim. The glass tube displaces some of the contents upwards when inserted, so the bottle should only be filled to the nominal volume stated in the specifications. The difference between the nominal and total volume is the allowance specifically for the dropper.
Is the dropper also suitable for thick gels or creams?
No, the dropper is not suitable for thick gels or creams. The silicone bulb draws them up slowly and unevenly, making dispensing imprecise. The dropper works best with liquid and slightly viscous contents such as oils, serums, tinctures, or concentrates; a pump or jar is more appropriate for thicker textures.
