The Edge Resin for Fibreglass or Silk 28g is a resin and mesh that combine perfectly and together they create a strong and thin overlay. The great thing is that Fibreglass or Silk Mesh can also be used to strengthen weak natural nails. Apply the mesh over the entire surface of the natural nail then coat with resin and Activator spray to create a strong, protective extra layer to soft and thin nails. A great way to rescue broken nails too!
