Review on 2-Pack Senignol Glass Nail File Set With Leather Case - Nano Crystal Shine Buffer And Polisher For Natural And Acrylic Nails - Professional Manicure Tools For Women And Girls by Joseph Swanson

These nano glass files are magical. I don't know how they work but they do. And they work very well. They smooth nails quickly without any rough edges or tears. They smooth and buff the nail surface as well. They also smooth/remove any bits of hardened skin that sometimes form around the nails quickly and efficiently. Rocking natural nails has never been easier thanks to these. I ordered more so I am never without and also to give to friends.The only minor drawback is they are glass and more delicate than metal and foam files. Each file comes with its own little faux leather case which helps to protect them. But if you drop them, they can chip and/or break.
