The crystal nail file is very smooth as it glides over the nail tip. It doesn't tear the nail like the emery board or metal file, so you can file in both directions and as an added bonus - no more jagged edges! When you file your nails with a crystal file, you'll notice how smooth the nail tip is.
The crystal file closes the nail tip and actually seals it, preventing water and debris from leaching into your nail. After using a crystal nail file for a period of about one month, users report a noticeable difference in their nails being stronger and they "don't chip and crack and peel as much".
Crystal is non-porous and very hygienic. No bacteria or debris can grow on the filing surface, nor get trapped in the roughened surface of the crystal file. The same is true for the crystal pumice file which can be left right in the bathtub without fear of mold, mildew, fungus or bacteria growing in it or on it!
The metal files cannot be sanitised to the FDA's satisfaction for the ultimate in cleanliness.
On the green-o-meter metal files score slightly higher than their cardboard friend because of the lack of trees used in its production. Metal does off-gas some nasty chemicals during the production process and metal files should be thrown out after several uses since they cannot be efficiently sanitised. They do take a lot longer than emery boards to decompose in landfills.
Your highest quality crystal files are cut from actual crystal and the surface of the crystal is treated in the manufacturing process to roughen it, creating the filing surface.
Because of the porous nature of the cardboard, glue and sand, dirt and debris can get embedded into the file and fungus and bacteria can grow rampantly. Though you might not see it with your eyes, a good micro-biologist and a microscope will enlighten you on your science project on a stick! There is no way to clean, let alone sanitize an emery board and they are so subject to bacteria that you should toss out your emery board after each use. This is the mandated practice per the FDA in professional salons and this bring us to the environmental factor. The emery board scores very low on the "green-o-meter". The number of trees used to make millions of files and the landfill space taken up by these little 5 inch sticks, is more enormous than you can imagine. At least one entire football stadium can be filled each year with tossed aside emery boards and it takes years for one to fully decompose in the ground.
