<Business Activities>
FOX was founded in 2011 and started with the import and sale of smartphone cases. Since then, we have built relationships with various manufacturers and factories worldwide, expanding our product categories. Currently, in addition to importing and selling smartphone cases, we are involved in businesses related to smartphone accessories, including the import and sale of Blackberry (smartphones) and IoT gadgets, supplying products as a supplier of fashion brand cases, and producing tablet devices for major telecommunications carriers.
Since its founding, FOX has adhered to the principle of "providing value to customers" rather than simply "selling products." We have sincerely engaged in each business with a marketing-oriented approach, achieving numerous successes. By sublimating the know-how and knowledge cultivated through our past businesses (such as reliable information gathering through networks, planning capabilities that quickly incorporate market needs, functional and high-quality manufacturing, distribution through high-quality sales channels like major telecommunications carriers and department stores, and building a CS team that plays a crucial role in customer contact), we continue to strive for the construction of a sound and robust supply chain in the smartphone-related field.
