this review title is: a little rough for natural nails and the content is: they say these are for artificial or natural nails but unless you have very hard nails or use them very gently you will not get as much use out of these as you would if you wear acrylic nails you get a range of colors in the box and i doubt that they are going to last very long very effective for shaping acrylic nails very quickly.there are other information for this review, one is this reviewer did not purchase it and the other is 0 people think this review is helpful.
