Manufacturing Partner: Karuson Eyewear Factory
I. Customer Background
Founded in 2010, Walleva Inc. (brand: walleva®) is a premier US-based sports eyewear brand. Operating through global third-party platforms and independent stores, Walleva has built a stellar reputation for excellence. Their rapid ascent to becoming a market leader was fueled by a vision for high-performance optics, supported by the robust manufacturing capabilities of a professional eyewear factory.
II. Core Collaboration Highlights
Phase 1: The Foundation—Reliable Quality from Day One

By delivering reliable polarized clarity and rapid response times, Karuson established the foundational trust required for a decade-long journey.
