This Salerno, Italy-area manufacturer of porcelain cups is a heavy hitter in the Napoli area - and yet they don't even have a Web site. They are generally unknown outside of their region, but within their region they are highly sought after by some of the finer cafés, coffee houses, and restaurants.
They also dabble a bit in coffee roasting, distribution, and even espresso machine manufacturing - although these aspects of the business are not nearly as prominent. They have adopted the slogan, "All that is worth doing must be done well." But it's unclear yet if that has translated to their non-porcelain businesses.
