Built in Zhejiang.Trusted Worldwide.
Two decades manufacturing export-quality eyewear from China’s eyewear capital — for brands who need reliability, not surprises.
Who We Are
We areZhejiang Three Hippos Glasses Co., Ltd(also registered asTaizhou Three Hippos Glasses Co., Ltd), headquartered in Linhai City’s Duqiao Town — the heart of China’s eyewear manufacturing belt.
Our factory runs three specialized production lines: metal frames, acetate frames, and injection-molded frames. That focus is intentional. When you specialize, you get better. When you get better, your clients come back.
Our clients are brands, buying groups, and wholesalers across Europe, North America, Australia, and Southeast Asia. They come back because we deliver consistently — not just on order one, but on order ten.
Every frame that leaves our factory passes through a computer-precision machining process with 99.9% tolerance and nickel-free, bio-compatible plating. Quality isn’t a selling point for us. It’s the minimum.
