Review title is I wear natural nails and the average file tears my nails up something terrible, causing splitting & cracking [SEP] Cute, but still a bit too harsh. I ordered because i purchased a crystal file at CVS & they don't carry it anymore & i can't recall the manufacturer.  I wear natural nails and the average file tears my nails up something terrible, causing splitting & cracking.  This doesn't quite do it. But if you have acrylic i guess it'd work out.
