Our History
Since the early 1950s, NSI parent company, AMCO, a family-owned concern, was the proud manufacturer of high-quality products for the dental and nail industry. NSI’s history started with humble beginnings in 1957 when Dr Slack (Fred Slack’s father) cut his thumb nail while working in his dental laboratory. Using aluminium foil, he created a platform to fix the nail with dental acrylic, which led to the patent of the nail industry’s first sculptured form.
