NSI HISTORY
For more than 40 years, NSI has been at the forefront of researching, developing and
manufacturing innovative products with cutting edge ideas for the professional nail care
industry. We have built a tradition on creating breakthrough products that nail technicians
choose to use.

JUST LOOK AT OUR HISTORY…
• 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 nonyellowing,
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, as well as air and heat activated polish sealants.
Our chemists continually meet the demands for innovative products.
• Fred Slack III, along with his sons Rick and Kirby, and an international team of field testers,
have been instrumental in the development of numerous NSI products. The company
owns the patent on Elation and French Fin Tips which utilizes Poly FlexTM, a unique material
that far exceeds the limits for tip performance.
• In going the extra mile for quality control, NSI requires batch and tracking numbers on all
products. If a nail technician does experience a problem, it can be quickly identified and
solved.
• Mandatory inspection of manufacturing procedures plus many levels of quality control
ensure that all NSI products maintain consistency from batch to batch.
