Treatment of nails is careful and of good quality

Proč skleněný pilník

Owing to the manufacturing technology the grinding surface of glass nail files consists of microscopic sharp spikes that are very evenly distributed on the surface. This way it is achieved that filing of nails with Czech glass nail files is gentle and considerate, yet efficient at the same time. The user does not have an uncomfortable feeling while filing. Nails are after treatment with crystal nail files smoother than after usage of ordinary paper of metal files, do not split and peel. Long-term usage of Czech glass nail files prevents nail chipping and contributes to overall well-being of the nails.

Czech crystal glass nail files do not blunt and wear out

The grinding surface of ordinary paper or metal nail files is formed of grinding grains attached to a base. The grains tend to fall off after some time; the file gets blunt and needs to be replaced. The grinding surface of crystal nail files is created right out of the file body, by chemical action onto the glass surface. This way a practically unlimited lifespan of crystal nail files is achieved.

Sufficient mechanical resistance

All glass nail files from our production pass during the production through hardening process (chemical hardening), during which their mechanical resistance is significantly increased. A certificate issued by an accredited laboratory confirms that the mechanical resistance of hardened glass nail files increases on average by 100 % in comparison with non-hardened files.

Hygienic standards of crystal glass nail files

Due to the material features the crystal nail files are not porous, which means that they do absorb water and multiplication of germs does not occur. Besides that the glass nail files can be disinfected, scalded out and sterilized by any means (heat, liquids like e.g. 60% ethanol, UV light). Even in aggressive conditions the properties of finger nail files are not influenced, the files do not suffer from corrosion or any other negative change of their properties. Decorated crystal nail files should not be exposed to solvents and temperatures over 200 °C, because under such conditions the decoration might deteriorate. The qualities of the file itself are not affected.

Professional usage

Two features of the crystal glass nail files are important for professional usage: firstly the excellent grinding properties of the crystal nail files, which guarantee quality and careful nail treatment, and secondly the feasibility of sterilization, which eliminates the risk of translation of skin and nail infections among the customers.


Material the crystal nail files are made of is flat glass of common composition, which does not contain any dangerous, deleterious or allergenic components. The health–safety of Czech crystal nail files has been confirmed by a certificate elaborated in an accredited laboratory of the National Health Institute of Czech Republic. In relation to the environment glass is an inert and easily recyclable material.

Czech crystal glass nail files are multifunctional

Proč skleněný pilník

Czech crystal glass nail files are primarily determined for filing and treatment of both natural and artificial nails (for artificial nails it is recommended to dip the file in water frequently). Crystal nail files can be used also for removal of callous skin in the heel or elbow area, for treatment of pets’ claws and in technical fields for gentle filing of softer materials like plastics or wood (e.g. in modelling). However, the crystal nail files are not suitable for materials harder than glass (like e.g. metals). In any application it stands that the resulting surface is highly smooth.
