Always fit the dropper onto a clean and dry neck rim of the bottle or vial. First screw it on gently until you feel the first resistance, and then tighten it only enough so that it holds well and no leakage of the contents occurs. Excessive tightening may shorten the service life of the sealing parts or cause deformation of the dripping system. After filling the container, we recommend performing a leak test by turning it upside down and shaking it briefly.

The dropper is suitable mainly for low to medium-viscosity liquids, such as common facial oils, liquid serums or aromatherapeutic blends. With thicker oils, dripping may be slower, or it may be necessary to slightly adjust the dosing method (by gently pressing the bulb or by holding the bottle in an inclined position for a longer time). Before launching into sale, we recommend testing the dosing with the specific formulation.

The dropper can be reused with the same formulation provided you observe hygienic principles during filling and storage. Before each new filling, the dropper and the bottle must be thoroughly cleaned and disinfected with a suitable alcohol-based preparation, for example using the products IPA 99 % isopropyl alcohol or ethanol 96 % denatured plant-based, available on the Handymade.sk website (IPA 99 % isopropyl alcohol 1 l, Ethanol 96 denatured plant-based 1 l). Disinfection helps minimise the risk of microbial contamination and extends the usability of your products.

If you decide not to reuse the dropper, we recommend disposing of it according to the recommendations given in the parameter table at the product on Handymade.sk. The recycling symbol and material type can be found in the product details. According to this marking, you will place the dropper in the appropriate separated waste stream or in municipal waste if the given material is not recycled at the collection point. Before discarding, it is advisable to remove any remaining contents and, where possible, separate the individual packaging components according to the materials used.

To select a suitable bottle, vial or other closure, you can use the advanced filter in the packaging categories. After clicking on the relevant category, the filter is located at the top of the page and allows you to sort the offer according to parameters such as neck type, size, colour and material. Thanks to the combination of these filters, you will quickly find compatible containers and accessories that will meet both the technical requirements and the design of your product.
