Review title is Love the cases [SEP] I'm 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 don't lose their effectiveness like the traditional emery boards. I'm also super happy to have the cases for them, even though they don't always snap real securely. They protect them from shattering or harming things they touch in my purse or manicure kit.
