The finest pores etched into a glass body form the even filing surface and enable very gentle filing. The glass nail file is therefore less suitable for shortening, but ideal for fine filing of nail edges and surfaces as well as for very sensitive nails. The file is made from so-called float glass, which is then further strengthened using a special ion exchange process. In this process, sodium ions in the glass surface are exchanged for potassium ions, creating a pressure-resistant protective layer. This gives the file a very high mechanical resistance and makes it particularly durable and break-proof in everyday use. A little care is nevertheless required when transporting the file. The glass nail file is produced in the Czech company that originally co-developed glass nail file technology.

As much as necessary, as little as possible. This sentence basically sums up what the natural cosmetics company Niyok stands for. Its body care products contain only the ingredients necessary for their purpose and are also vegan and certified as natural cosmetics. But the North Rhine-Westphalian manufacturer goes one step further than usual for maximum transparency: on the back of the packaging of the body care products, the so-called INCI list, which shows all the ingredients of a product with the technical name, is not only displayed, but all the names of the ingredients are also translated and briefly explained. This is also what Niyok understands by transparency: not only seeing what's in it, but also understanding it. The company motto could just as well be: minimum formulation, maximum transparency.

All Niyok body care products are produced at the company's site in Germany - with green electricity, and all but a few of the manicure instruments are carefully selected and, where possible, come from Europe. This also ensures clean and fair production conditions. Parabens, silicones and palm oil are, of course, taboo.

It goes without saying that, with a few exceptions, plastic is not used in the packaging - but this is not a matter of course. For example, Niyok is one of the few manufacturers whose manicure instruments are supplied in plastic-free packaging. The toothpaste tubes are made of 50% chalk and 50% polyethylene. This means that the walls of the chalk tube are only half as thick as those of conventional plastic tubes. And wherever possible, glass or cardboard is used instead of plastic or no packaging is used at all.

Niyok also supports the Berlin-based company CleanHub. Its digital platform for waste traceability enables comprehensive monitoring of plastic collection activities. This software tracks every kilogram of plastic waste from the point of collection to disposal. CleanHub thus contributes to transparency in collection and helps to finance the costly collection of different types of plastic and their recycling.
