Durable & Reliable Clip On Frame Construction
A clip on frame is an item of frequent use, so durability is non-negotiable. Tuopu builds reliability into every component. The frame front is constructed from high-grade nylon or Grilamid, materials chosen for their exceptional fatigue resistance—they can be clipped on and off thousands of times without losing their shape or tension. The hinge points of the clips are reinforced and undergo cyclic testing to prevent failure. The lenses are coated with a hard, scratch-resistant layer to maintain clarity. We subject our clip on frames to real-world stress tests, including temperature extremes and impact tests. This rigorous approach ensures you are supplying an accessory that won’t fail your customers, protecting your brand from returns and building a reputation for products that last.
