I love this product because not only does it file your nails, but it buffers, polishes, and shines your nails, pretty much it's a shaping tool for your nails! The first time I used this product I was amazed at how awesome my nails looked, I basically gave myself a nail treatment similar to what a nail technician would do in a nail salon.
There are many variations of this product, I've found a few similar ones at Big Lots for a lot cheaper but they don't work as well as the Sephora one! For only $5.00 it is definitely worth it, you can check it out here on the Sephora site. Do you own the Sephora 4 Step Nail Buffer? Do you use anything similar to file/buffer/polish/shine your nails?
