Roll-On Ball for 5 ml

The 5 ml roll-on ball is a replacement and accessory part for 5 ml roll-on bottles. It sits in the insert at the bottle neck and, when moved across the skin, applies the contents in a thin, even layer. It is suitable wherever a product needs to be applied precisely and in small amounts: perfume oils, essential oil blends in a carrier oil, eye serums, lip oils, or targeted nail and cuticle care.

A spare ball is particularly useful when the original one is lost or damaged, or when the bottle is refilled repeatedly and the ball should be replaced with a new one.

How it dispenses as a roll-on

The ball rotates freely inside the insert and lifts a thin film of liquid from the bottle onto its surface. The amount of product applied depends mainly on the viscosity of the contents:

• Light oils and oil blends – applied smoothly and evenly; the most common fill for roll-ons.
• Aqueous and alcoholic solutions – dispense more generously; with very thin contents, check whether the bottle leaks during transport.
• Thick gels and emulsions – the ball picks these up poorly or unevenly; only fluid, easily spreadable textures are suitable for roll-ons.

Good to know

Preparation before use. Before first assembly, wash the ball, disinfect it with isopropyl alcohol or ethanol, and allow it to dry completely. Any remaining water or disinfectant would otherwise get directly into the product.

Assembly. Press the ball into the insert with even pressure until it clicks into place. The insert with the ball is then pressed into the neck of the filled bottle. Once assembled, the ball should rotate freely and must not fall out of the insert.

Filling the bottle. The nominal volume is the amount the bottle is designed to hold under normal filling conditions. The total brim volume is the physical capacity up to the neck and is slightly larger. This difference serves as a reserve for the insert with the ball and for the expansion of the contents with temperature changes.

Compatibility. According to the technical documentation, the ball is suitable for use with cosmetic products and meets the relevant regulatory requirements. It is designed for 5 ml roll-on bottles from the Handymade range, where complete sets are also available. When combining with a different bottle or insert, we recommend verifying the dimensions stated in the specifications, the seal, and the behaviour with the specific formulation.

Reuse. When refilling, remove the ball from the insert, degrease it, disinfect it, and dry it. If the surface is scratched or the ball no longer rotates smoothly, replace it with a new one.
