Sephora Brand Glass Nail Files Purple

I bought my nail file in Prague, so I assume it is the genuine article but it has worn out after almost no use! By the time I had had it for three months and used it not much at all there is an obvious bare patch down the middle of the file, and I'm forced to search for rough bits which still work! I'm very disappointed in this item. I bought it so I could take it on planes but it won't be any use for another trip.

We have used glass nail files for several years and they cut nail edges very clean. Sephora ships their Glass Nail file in a soft plastic envelope with no packing. It arrived in four pieces and they will not replace it. They will refund the cost of the file, but not the shipping which is as much as the file.
The other brand purchased through Amazon arrived intact even though the BOX was brutalized by UPS, and it has both sides of the file useable.
If you like them, I would recommend the Crystal brand.

I was very disappointed in this product. I have another brand name glass nail file and it is a million times better. And plus, only one side has a filing side.

Another awesome item recommended by my manicurist. It doesn't wear out like emery boards do and it's not as harsh as a metal file. It does a great job.

What is nice about this product has nothing to do with its efficacy and everything to do with its lifespan. In fact, it can take a bit of time to even get used to the feeling, but I've had the product for 5 months and it hasn't even shown a sign of wear after weekly use.
Probably the biggest downside to the product is that since it doesn't wear down the nail dust clings to it. Every handful or so of strokes you will need to wipe it off, so it really requires some cloth to go with it.
Despite the few annoyances (sometimes it feels like scratching a chalkboard), it is -definitely- worth it. You will save some money if you currently use emery boards.
