Very Rough!  Doesn't file nails!
I don't know how these got 4 stars!  I bought for small gifts, but the surface of these files are VERY rough and when I tried it on my nails it didn't even wear down my nail.  You have to press against your nail and then you get action, but the finished product is not smooth, but rough and even jagged!  I WOULD NOT give them to anyone or use them myself.  I do not recommend these at all!!!
