NSO
NSI Australia (operating via nsinails.com.au and based in the Gold Coast warehouse in Arundel, QLD) is the Australian subsidiary of Nail Systems International (NSI), a globally recognized professional nail brand. With heritage dating back to the 1950s, NSI Australia offers salon-grade acrylic, gel, tools, and educational support to nail technicians across Australia and New Zealand.
Company History
NSI was founded in the United States in 1957 by chemist Fred Slack and his son Rick Slack, originally developing dental polymers that evolved into pioneering nail enhancement systems. NSI introduced many industry-first innovations, including the first non-yellowing powder/liquid acrylic, fiberglass-reinforced polymers, and light-activated gel systems. By the late 1980s, NSI was a fully branded nail manufacturer known for high-quality monomers and polymers.
NSI Australia began operations more recently, importing NSI’s full professional range and establishing a warehouse in Arundel, Gold Coast. The Australian division manages online distribution, showroom pickups, and trade support tailored to local nail artists.
