"My nails have always been extremely thin and brittle. If I touched something with too much force, they would tear, bend, or break. On top of that, I have been a nail biter my entire life. I tried EVERYTHING- icky tasting nail polish, Tabasco, nail hardener, etc. Nothing worked. I tried KILLER NAILS and OH-EM-GEE! My nails are so strong, healthy, and growing so quickly- and my urge to bite them has completely gone away because of how beautiful they are!!! I am so in love with the product I cannot imagine life without it. For anyone with brittle short nails, try this! You won't be disappointed."
