Ultra Limited has a new agent for the Netherlands, Optical Agency, and it is about to sign up with a distributor in the U.S. It already has distributors in Germany and Austria. All the glasses sold under the Italian brand, which is owned by a four-year-old company, 450Vision, are unique because they are made with a special process based on gluing together sheets of Mazzucchelli acetate in different colors. The company grew rapidly last year to €2 million, producing 30,000 pairs for the Italian and international market.
