SoftNLux [2-in-1] NUDE NAIL Glass Nail File & Shiner + Storage Case | A File & Shiner that Instantly Gives Your Nails A Glossy, Polished Look | Patented Special Glass | Made in Korea

LOVE this! The size is perfect to carry around in my purse for quick touch-ups and I love that it comes with its own case. It files my nails really well without that uncomfortable roughness you usually feel with those metal/emery boards. It also functions as a nail shiner - you can see the before and after in the pictures. Kind of tricky at first but after the first nail, it's easy peasy. I suggest you start from one side and work your way across the nail so that you polish evenly. It's about 3.5 inches long. Definitely worth it.

Excellent product and very useful.
