Acrylic nails also known as fake nails, false nails, fashion nails, nail enhancements, nail wraps, or nail extensions, are coverings placed over fingernails as fashion accessories. Some artificial nails attempt to mimic the appearance of real fingernails as closely as possible. While other designs may deliberately stray in appearance from real fingernails. Artificial nails are made from a wide variety of materials. Unlike most manicures, artificial nails require constant upkeep, and is recommended that you get a “fill” every 2 weeks.
