I received a free pack of these nails from another site and was asked to honestly review them. I am not a huge fake nail person, i am growing out my natural nails, so fake nails worry me as far as damaging my natural nails. I read on the pack of these nails that they will not hurt natural nails, so I tried them. Thankfully they did NO damage!! I am so impressed. NO DAMAGE AT ALL. These nails also last a long time and are nice and strong.
