Finding the balance between "Sustainability" and "Price" is tough. But this material combination solves that specific headache. It’s not just about mixing materials; it’s about putting the right material in the right place.

Here is the logic behind the design:

The Front (Eco-TR): We use TR material here for one main reason—Weight. It keeps the frame structure stable but significantly lighter than full acetate, preventing the glasses from sliding down the nose bridge.

The Temples (Acetate): This is where the quality is felt. Unlike basic plastic, acetate temples contain a metal wire core. This allows opticians to heat and adjust the fit behind the ears—a non-negotiable feature for professional eyewear.

You get the technical performance of injection molding combined with the premium touch of craftsmanship. It is the smartest way to keep your catalog "Green" without forcing your customers to pay luxury prices.
