Green Glass Bottle with Roll-On, 10 ml

The green glass bottle with a roller ball and a black cap is a complete packaging set for 10 ml of liquid product applied directly to the skin with a roller. Green glass filters part of the light, so it suits contents that are sensitive to light, for example fragrance oils, essential oil blends in a carrier oil, or oil serums for nails and cuticles. The set includes the bottle, a steel ball in a plastic seat, and a cap that covers the ball after use and protects the contents from drying out and from dirt. All three parts are declared suitable for contact with cosmetics.

What the roll-on is suitable for

The roller dispenses the contents in small amounts and applies them to the exact spot without your fingers touching the contents. It is therefore particularly suitable for:

• Roll-on perfumes and fragrance oils – applied to the wrists, neck or behind the ears, with no spilling of the contents.
• Essential oil blends in a carrier oil – for example for the temples, nape or wrists, where only a few drops need to be applied.
• Oil serums for nails and cuticles – the ball spreads the oil directly around the nail bed.
• Topical oil-based or alcohol-based preparations – applied to a small area of skin without a cotton pad or dropper.

A roll-on only works with liquid contents that the ball can transfer to the skin as it turns. The roller handles oils, alcohol solutions, water-based solutions and thin serums. It cannot push through thick gels, creams and balms, and the contents will not reach the skin.

Bottle volume

The nominal volume of 10 ml is the volume the bottle is designed for in normal filling. The brimful volume is the physical volume up to the neck, and you will find it in the parameters. The difference between them is a reserve for the ball seat, which pushes part of the contents upwards when it is inserted, and for the expansion of the contents with changes in temperature. Fill up to the nominal volume, not to the brim.

How to work with the set

Before the first filling, wash the bottle, the seat with the ball and the cap, disinfect them with isopropyl alcohol or ethanol, and leave them to dry completely. Pour the contents into the bottle, press the seat with the ball into the neck and screw the cap onto the 18/410 neck finish. Before first use, turn the roller several times so that the ball is wetted.

Glass is resistant to oils, alcohol and essential oils. The ball seat and the cap are made of polypropylene, and the ball is steel. For contents with a high proportion of undiluted essential oils or with solvents, we recommend checking whether the plastic parts change shape after prolonged contact and whether the set still seals.

Good to know

• Seal – before carrying the bottle in a bag, when transporting a larger number of pieces, or with very thin contents, check that it seals with your specific formulation, ideally by laying the filled bottle on its side.
• Reuse – once empty, the bottle can be washed and filled again. The ball seat may be damaged when it is prised out of the neck, so check that it seals after reinserting it.
• Water-based contents – the ball also spreads water-based solutions and hydrosols, but such a formulation must be preserved.
• Other closures – the bottle has an 18/410 neck finish, and you will find closures with the same neck type, as well as ready-made combinations, in the Handymade range. If you make your own combination, we recommend checking the seal and the dispensing.
• Recycling – glass goes with glass, the cap with plastics, and the ball seat is a combination of plastic and steel.
