Clear Glass Bottle with Roll-On, 10 ml

The glass roll-on bottle with a roller ball, 10 ml, is used to apply liquid preparations directly to the skin, without dripping and without touching them with your fingers. The set consists of a clear glass bottle, a steel roller ball in a plastic seat, and a black cap with an 18/410 neck finish. Through the clear glass you can see both the colour and the remaining amount of the contents. The volume suits fragrance oils, aromatherapy blends diluted in a carrier oil, lip oils or light oil-based eye serums. The whole set is declared suitable for contact with cosmetics; it is not intended for food.

What it is suitable for

• Fragrance oils – the ball spreads a small amount onto the wrist or neck, the fragrance is dosed precisely and nothing spills onto the skin or the table.
• Aromatherapy blends – essential oils diluted in a carrier oil, applied to the temples, nape of the neck or wrists. The roll-on is a well-established format for such blends.
• Oil for lips and the skin around the nails – the ball applies a thin layer without you having to scoop the oil up with a finger.
• Oil-based eye serums – the cooling touch of the steel ball suits gentle tapping around the eyes, provided the formulation is fluid enough.
• Samples and travel packs – the small volume and the closed ball withstand being carried in a bag, and the cap covers the ball.

How to use a roll-on

Fill the bottle with the prepared formulation, press the insert with the ball firmly onto the neck and tighten the cap. Before first use, roll the roll-on over the skin several times until the ball is wetted by the contents and begins to apply evenly.

The viscosity of the contents is decisive. Carrier oils such as jojoba, almond or fractionated coconut oil, fragrance oils and light oil-based serums flow smoothly around the ball. Thick balms, butters or gels that do not flow at room temperature are not picked up by the ball and the insert becomes blocked. Very thin, water-based contents, on the other hand, may escape around the ball when the bottle is turned upside down. Therefore, test the seal with your finished formulation on a single piece before you fill the whole batch.

The nominal volume is the amount the packaging is designed for with normal filling. The total brimful volume is the physical volume up to the neck, and the difference between them is a reserve for the insert with the ball and for contents that expand in the warmth. If the bottle is filled to the brim, part of the preparation will overflow as soon as the insert is fitted.

Good to know

Before the first filling, take the packaging apart, wash the bottle and the insert, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual water under the ball does not belong in oil-based contents.

The ball seat and the cap are made of polypropylene (PP), the ball is made of steel. For blends diluted in a carrier oil, such a roll-on is a commonly used format. For undiluted essential oils, contents with a high proportion of citrus oils or alcohol-based formulations, we recommend checking the behaviour of the plastic and the tightness of the seal with your specific formulation.

For repeated use, carefully release the insert from the neck, then wash and disinfect the set. If the ball does not turn smoothly after cleaning or the insert does not sit firmly on the neck, it is better to replace it than to risk leakage.

The bottle has an 18/410 neck finish; you can find further closures for this neck and ready-made combinations in the Handymade range. If you make your own combination, we recommend checking the seal and dispensing with your formulation.

For recycling, the glass bottle belongs with glass; separate the plastic insert with the steel ball and the cap from it before disposal.
