Clear Glass Bottle with Roll-On, 5 ml

The glass roll-on bottle with a volume of 5 ml is supplied as a ready-made set: a clear glass medicine bottle, an insert with a metal ball and a black plastic cap with an 18/410 neck finish. It is used for liquid preparations that are applied directly to the skin in small amounts, especially perfume oils, blends of essential oils in a carrier oil, spot serums or cuticle oil. Clear glass shows the colour and the remaining amount of the contents, which is useful for samples and trial batches where fragrances and shades are compared. The small volume also suits travel packs and gift sets.

How the set works

Once the bottle is filled, the ball insert is pressed into its neck, where it stays in place without being screwed in. When the bottle is turned over and rolled across the skin, the ball applies a thin layer of the preparation without dripping and without your fingers touching the contents. The steel ball feels cool to the touch, which is why a roll-on is often chosen for the temples, wrists or neck. The cap is screwed over the insert onto the thread of the bottle, protects the ball from dirt and keeps the set closed in a handbag or travel bag.

The set is declared suitable for contact with cosmetics, and the declaration of conformity and technical documentation are available with the product.

Nominal and total volume

The nominal volume is the amount the bottle is designed to hold in normal filling, in this case 5 ml. The total volume to the brim is the physical volume up to the neck, and you will find it in the parameters. The difference is a reserve for the ball insert, which takes up part of the neck once it is pressed in. For this reason, fill the bottle up to the nominal volume, not to the brim, otherwise the preparation will overflow when the ball is fitted.

What it is suitable for

• Perfume oils – a fragrance composition diluted in a carrier oil, for example jojoba or fractionated coconut oil, is applied precisely to the pulse points with a roll-on, without waste.
• Aromatherapy blends – essential oils diluted in a carrier oil at a usual usage rate, ready to use without measuring out drops.
• Spot serums and oils – cuticle oil, nourishing lip oil or spot care for minor imperfections, where a few passes of the ball are enough.
• Samples and travel packs – 5 ml is enough for trying out a new composition or for a trip of a few days.

Good to know

Before the first filling, wash the bottle, the ball insert and the cap, disinfect them with isopropyl alcohol or ethanol and let them dry completely. Residual moisture does not belong in an oil-based preparation, and in a roll-on it settles under the ball.

A roll-on is designed for liquid oils and thin solutions. Thick balms and gels will not flow past the ball. Very thin alcohol solutions, on the other hand, may seep around the insert faster than desired. The cap and the insert are made of polypropylene, so with concentrated essential oils or solvents, watch whether the plastic parts change shape or colour over time.

The glass bottle can be reused. When you change the fragrance, remove the ball insert and clean it thoroughly, because residues of the previous composition cling to the space under the ball. You will find closures with the same neck type and other ready-made combinations in the Handymade range. At the end of its life, the glass belongs in glass waste, and the plastic parts with the ball are sorted separately.
