I saw this product in Dis Chem quite a few times and I never thought to purchase it, so this past weekend I decided to give it a try! I was impressed. The file has a slight curve which makes it easier to shape nails, plus it doesn't damage nails and I was impressed that the file is actually quite strong, because normally when I file my nails I mess everything with file dust, but surprisingly with this file nothing got messed and no dust fell anywhere. Plus if you want to take this product, it has a nifty casing which stores the file safely.
