this review title is: love the cases and the content is: i am sold on the crystal nail files been using this type for a long time and they seem much more gentle on my nails while still quickly filing and keeping their texture they do not lose their effectiveness like the traditional emery boards i am also super happy to have the cases for them even though they do not always snap real securely they protect them from shattering or harming things they touch in my purse or manicure kit.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
