Clear glass roll-on, black cap, metal roller ball, 5 ml

A glass roll-on with a capacity of 5 ml is designed for precise, targeted application of liquid cosmetic preparations directly onto the skin, without dripping and without finger contact. The set consists of a clear glass bottle, a steel ball and a black screw cap. The small volume is well suited to pocket-size packaging, samples and preparations that are applied in small amounts.

Clear glass shows both the colour and the remaining quantity of the contents. The metal ball glides smoothly across the skin and feels pleasantly cool on contact, which is particularly appreciated in preparations for the eye area and temples.

What products is the roll-on suitable for

• Oil perfumes and fragrance blends – the ball deposits a thin film on the wrist or neck, so the concentrated scent is dispensed economically.
• Essential oil blends in a carrier oil – aromatherapy roll-ons for the temples, wrists or neck; always diluted blends, never pure essential oils.
• Eye area serums – both oil-based and light aqueous serums, which the ball applies without pulling the skin.
• Cuticle and lip oils – a small application area where a single roll of the ball is sufficient.

How the set dispenses and seals

The ball sits in the neck of the bottle and, as it moves across the skin, draws up a thin layer of the contents. The amount dispensed depends on the viscosity of the preparation:

• Light oils and lightweight serums apply evenly.
• Very thin aqueous or alcoholic liquids flow more quickly and may deposit more product than needed with a faster stroke.
• Thick gels, emulsions and preparations containing solid particles will slow down or block the ball.

The cap screws onto the bottle thread. When tightened, it seals the bottle and protects the ball from dust and contaminants.

Nominal and total volume

The nominal volume is the quantity the bottle is intended to hold during normal filling. The total brim-full volume is the physical volume of the glass up to the neck and is slightly larger. The difference serves as a buffer: the ball, once pressed into the neck, takes up part of the space, and the contents expand slightly at higher temperatures. The bottle should therefore be filled to the nominal volume, not to the brim. Otherwise the contents will overflow when the ball is inserted.

What to know before filling

• Preparation – wash the bottle, ball and cap before first use, disinfect with isopropyl alcohol or ethanol and allow to dry completely. Residual water reduces the stability of oil-based preparations.
• Filling – a small funnel or syringe helps with the narrow neck. The ball is inserted only after filling and pressed into the neck with even pressure.
• Aqueous and acidic contents – with a steel ball we recommend verifying through a long-term test that neither the appearance of the metal nor the preparation changes.
• Label – the cylindrical body has a small circumference; the dimensions needed for label design can be found in the product specifications.
• Intended use – all parts of the set are declared suitable for contact with cosmetic products. The set is intended for cosmetic use.
• Sorting – separate the glass bottle, steel ball and plastic cap before disposal.

Separate bottles, balls and caps with the same neck type are available in the Handymade range. With a custom combination, we recommend verifying the seal and dosage with your specific formulation.
