Fiberglass... Fiberglass nails, also known as silk wraps, involves the use of thin, flexible products made from silk, fiberglass or other fabrics. Fiberglass nails and silk wraps are both applied the same way - the only difference between the two is the type of fabric used for the nail reinforcement. While silk appears less noticeable, fiberglass tends to be slightly stronger.

About Fiberglass:
In a world of gel extensions and acrylics, fiberglass is a less common method for adding temporary length to nails. Fiberglass is a thin, cloth-like material that is usually separated into teeny-tiny strands. To secure the cloth, your nail artist will paint resin glue along the edge of the nail, apply the fiberglass, and then add another layer of glue on top. The glue hardens the fabric, which makes it easy to shape the extension with an emery board or nail drill. Once your tips are sturdy and shaped to your liking, your artist will then sweep acrylic powder or gel nail polish over the cloth.
