Prepare the contents in a separate container and pour them into the bottle using a funnel or a dosing pipette to avoid contaminating the neck. Do not fill the bottle completely to the top – leave a small air gap that will make it easier to attach the roll-on insert. Insert the ball module according to the recommended procedure (by pressing evenly), then close with the cap and turn the bottle several times so that the ball is evenly coated with the product. Before full-scale introduction to sale or use, we recommend a trial batch to verify sealing and smoothness of dosing.

The packaging can be reused if correct hygiene practices are followed. Before each new filling, the bottle, insert and closure must be thoroughly washed, rinsed and then disinfected with a suitable alcohol-based preparation, for example IPA 99 % isopropyl alcohol or ethanol 96 % denatured plant-based. After disinfection, let all parts dry completely at room temperature. When reusing, always check the condition of the ball and the sealing; in case of visible wear, it is advisable to replace these components in order to maintain dosing functionality and product hygiene.

The roll-on bottle is ideal primarily for oil-based and low-viscosity blends that are to be applied locally in a thin layer. It is perfectly suited for perfume oils, aromatherapeutic blends in a carrier oil, facial and body oils for massaging specific areas, and caring blends for nails or problematic skin zones. For very thick or gel-like textures, the movement of the ball and the product output may be limited, so it is important to always verify in advance the compatibility of the formulation with the specific roll-on system using a trial batch.

If you decide not to reuse the packaging, we recommend sorting it into separated waste according to the material specified in the product parameters. The glass body of the bottle usually belongs in the glass container after removing any residual contents. Plastic or metal parts of the closure and roll-on insert should be separated and discarded according to local rules for sorting plastics or metals. Before recycling, it is a good idea to rinse the packaging to minimize residues of the cosmetic product. You should follow the instructions in your town or municipality and the recommendations resulting from the material designation in the parameter table for the product on Handymade.

To choose suitable packaging, you can use the advanced filter, which you will find at the top of the page after clicking on a specific packaging category. In this filter, you can easily select parameters such as neck type, size, color and packaging material, and thus narrow down the offer only to bottles, jars or pots that correspond to your product. Thanks to the combination of several filters, you will quickly find packaging that will suit your formulation, design and dosing method.
