Bought a cheap version to try the concept & paid for it! [SEP] I had never used a glass cuticle file before, ev,n though I have probllem cuticles and have tried many other products to help them.  First I want to say that I definitely reccomend a glass file/pusher for dried, cracked nails; it cleaned out the dried gunk very quickly.  I did damage my heathy skin a little, but that was because, I was pushing too hard--I figured it out eary in my first manicure.  This tool can be used to clean cuticles, smooth nails, and sand down tiny hardened hang nails, and--used gently--do it safely.<br /><br />My complaint is that, on its very first use, this cheap Chinese tool developed a large chip in the nail pusher end.  Now that I know I like the glass tool, I will buy one of tempered Czech glass.
