My Tai Large Glass File for Toe Nails and Pumice File.
This glass file is more coarse than the small and medium glass nail files and was designed to file and shape thick toe nails and the occasional fixing of an article nail tip. The Large Glass File is also an excellent Pumice File to remove calluses on your hands.
Top Notch Nail Files only sells the authentic patented glass files from Czech Republic. Authentic files are marked by a holographic sticker bearing the PATENT NUMBER on the sticker.
