Since 1957, NSI has been a family owned and operated manufacturer of high quality monomers, polymers, and other enhancement products for the professional nail industry.

As early developers, inventors, and chemists, NSI pioneered and developed the first non-yellowing, cross linked formulations used in all traditional acrylic systems today.

As pioneers, NSI was the first to introduce fiberglass-reinforced polymers, light activated liquid and powder acrylics, UV-cured gels, and air and heat activated polish sealants. Our chemists continually meet the demands for innovative products.

NSI has proudly been manufacturing quality professional only nail products in America for over 25 years. All NSI Products are made in small batches with care and are quality tested to the highest standards to ensure all of our products stay consistent from batch to batch. We never test our products on animals and we never will. NSI is committed to providing the highest quality products to our most valuable resource: the nail technician. We listen to nail professionals to understand your needs as we pursue better nail chemistry, better techniques and faster applications to help you succeed. You ask, we answer.
