this review title is: they work ok on natural nails and the content is: these work okay on natural nails but they do not seem to last as long as some of my older ones that are still in use years later i generally only use them to touch up rough edges or file down broken nails but i could not swear to their durability i cannot imagine them working well on acrylics or gels but since i am not using either right now i can only attest to the fact that they are working on my natural nails and seem to work okay i am just not sure about their durability.there are other information for this review, one is this reviewer did not purchase it and the other is 1 people think this review is helpful.
