We do not randomly outsource your order. Each frame follows a structured handling and inspection workflow. From arrival to return shipment, your glasses are handled with care.
Our 3-Stage Quality Control System
Quality assurance is built into every step of our process.
1️⃣ Frame Integrity Inspection
Upon arrival, we inspect your frame for:
