Review title is They work ok on natural nails [SEP] These work okay on natural nails but they don't 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 couldn't swear to their durability. I can't imagine them working well on acrylics or gels but since I'm 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'm just not sure about their durability.
