Before Su and Fitz opened Fitzsu they collected magazine article of product they wanted to sell in their future store. One of those items was a calculator from the Japanese company Amadana. After opening Fitzsu Su tried endlessly to get in touch with the company with no success. One day while visiting a Japanese Art exhibition in LA Fitz came across a young Japanese girl who was using the Amadana calculator he so desired. As luck would have it the young lady was a friend of the owner of the company. A few months later he was visiting the US and came to the Fitzsu store to check it out. Amadana manufactures an extremely large amount of products, but the owner had no problem recognizing what Su and Fitz were trying to create. With his help and blessing Fitzsu now sells the Amadana products that Su and Fitz personally select for their store.
