Flex Protect Nail System is a UV cured “rubber” type finish that unlike traditional gel products allows bendable nails that are strong yet flexible. Polish lasts as long as the Flex Protect itself, which is usually up to two weeks. This product can be “filled” as it grows out. This is a lovely alternative to artificial nails. It gives a strong protective coating so your own nails can grow underneath without the damage associated with most Gel and Acrylic products.
