Glass roll-on, clear, silver cap, metal ball, 5 ml

This glass roll-on with a 5 ml capacity applies its contents with a ball directly onto the skin in a thin, even layer, without dripping and without touching with the fingers. It is suited above all to oil serums, perfume oils and blends of essential oils in a carrier oil that are applied to small areas: the eye area, temples, wrists or nail cuticles.

The set consists of a bottle made of clear glass, a steel ball and a silver cap. Clear glass shows both the colour and the level of the contents, but it does not protect them from light. The metal ball rolls smoothly across the skin and the cap protects it from dirt.

What the roll-on is suited to

• Oil serums for the eye area and lips – the ball applies a small amount exactly where it is needed.
• Perfume oils and oil-based perfumes – applied to specific spots on the wrists and neck; the small capacity is practical for samples and travel packs.
• Aromatherapy blends – essential oils diluted in a carrier oil for the temples, nape or wrists.
• Oils for nails and nail cuticles – the roll-on dispenses sparingly and the oil does not run off the treated area.

Filling and capacity

The figure of 5 ml is the nominal capacity, that is, the amount the bottle is intended to hold under normal filling. The total capacity to the brim is somewhat larger, because it also includes the space in the neck. This reserve is needed by the ball, which is pressed into the neck after filling, and by the contents, which expand slightly with heat. The bottle is therefore filled to the nominal capacity, not to the brim, otherwise the contents will overflow when the ball is seated.

What is worth knowing

The roll-on works well with thin to medium-viscosity contents, that is, with oils, oil serums and thin emulsions. Thick gels, creams and butters cannot get under the ball. Very thin alcohol-based blends, on the other hand, may run out faster than is comfortable during application. With your own formulation it is worth filling one unit as a test and checking both the dispensing and the seal.

Before the first filling it is recommended to wash and disinfect the bottle, ball and cap and let them dry completely. Glass does not tolerate sudden changes in temperature, so do not pour hot blends into it and, after washing in warm water, do not rinse it with cold.

The set is intended for cosmetic products.
