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.

It all started with Dr Frederick Slack, a leader in the prosthetic dentistry and the original developer of plastic teeth, cut his finger and his nail while working. He then made a platform from aluminium foil to create a nail form and dentistry products to build a new nail.  This action lead to the world’s first nail form in 1950.
