The glass bottle with roll-on applicator is generally suitable for formulations with a higher proportion of essential and perfume oils, since glass is materially stable and less prone to interactions with the contents. Nevertheless, we recommend performing your own compatibility test for every new formula – check the long-term stability of fragrance, colour and viscosity, as well as the functionality of the roll-on mechanism under normal use.

The glass packaging can be reused if hygienic principles are observed. Before each new filling, first clean the bottle and individual components mechanically, rinse them thoroughly and allow them to dry completely. We then recommend disinfecting the packaging with a suitable alcohol-based preparation, for example isopropyl alcohol or ethanol – in the range you will find, for example, the products IPA 99 % isopropyl alcohol and Ethanol 96 % denaturovaný rastlinný. Allow the disinfectant solution to act briefly, then let the packaging dry naturally and only then fill it with the new product.

The roll-on bottle is most suitable for liquid and less viscous preparations that can flow smoothly under the ball during application. These are mainly oil serums, perfume oils, light oil blends with essential oils and liquid products intended for local application to the skin. With significantly thick emulsions or balms, roll-on application may be limited, so it is advisable to first test the behaviour of the specific formula in the packaging.

To select 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 (for example bottles, jars or medicine bottles). In the advanced filter you can clearly set parameters such as neck type, required size, colour and packaging material. This will help you quickly find packaging that corresponds to your formula, the required dosing and the visual style of the product.

The filled glass bottle benefits most from storage in a dry place, at a stable room temperature and away from direct sunlight or heat sources. Always close the packaging carefully to minimize the product’s contact with air and dust. For products with a higher proportion of volatile substances (for example perfume and essential oils), it is particularly important to tighten the closure well so that the fragrance and stability of the blend are preserved for the entire period of use.

If you decide not to reuse the bottle, first remove any remaining contents after emptying and rinse the packaging. The glass part can then be placed in the appropriate glass collection container according to locally applicable waste-sorting rules. Other components, such as the roll-on mechanism or plastic closure, should be sorted according to the material type stated in the product parameters on the Handymade.sk website. By following the recommended sorting, you support effective recycling and the reduction of waste volume.
