Thin glass file made of quality toughened Czech glass (2 mm thick, 135 mm long, both sides toughened, sharp end). The file is not very coarse, which makes it perfect for manicuring all types of natural nails. A glass file does not damage the edge of the nail, but fuses it together. The Mereneid glass file is suitable both for home and professional use. The glass file can be washed, disinfected and sterilised. It is also very durable, but may break if dropped. The product is made in the Czech Republic and bears the stamp of the famous Bohemian glass region.
