Yes, the glass bottle is suitable for packaging both oil-based and watery formulations, such as serums, oils, extracts or concentrates, provided these products are chemically compatible with glass. Before final filling, we recommend carrying out a trial filling to verify the stability of colour, scent and consistency under the specific storage conditions.

The dropper is designed for precise dosing of a small amount of product, drop by drop. After opening the packaging, squeeze the rubber part of the dropper, immerse the glass part into the product, and by releasing the rubber, draw up the liquid. When applying, gently squeeze the dropper to achieve even, controlled dosing without splashing or unnecessary waste.

The bottle can be reused if hygiene principles and proper cleaning are observed. Before each new filling, the packaging must be thoroughly cleaned and disinfected, ideally using alcohol-based preparations such as IPA 99% isopropyl alcohol or ethanol 96% denatured, plant-based. Make sure the interior and the dropper are completely dry so that no residual water or cleaning agent remains in the packaging, which could affect the stability of the new formulation.

If you decide not to reuse the packaging, we recommend recycling it according to the instructions given in the product parameters. The glass part of the bottle, usually after rinsing off product residues, belongs in the container intended for glass. The other parts of the dropper (plastic, rubber or other material) should be separated and sorted according to local waste separation rules. Always follow the recycling symbols and the information stated with the product on the Handymade website to ensure the most responsible handling of the packaging.

When choosing suitable packaging, we recommend using the advanced filter, which you can find at the top of the page after clicking on the relevant packaging category. In the advanced filter, you can easily set parameters such as neck type, size, colour or packaging material and quickly narrow down the selection to bottles, jars or pots that best match your product and the technical requirements of the formulation.

Always store filled bottles well closed, in a dry place and away from direct sunlight and heat sources to minimize the risk of deterioration of product stability. Storing them in an upright position reduces the long-term contact of the dropper with the contents, which is particularly suitable for formulations with a higher proportion of volatile or more sensitive components. For each new recipe, we recommend carrying out internal stability tests under the conditions in which the product will actually be stored and used.
