Explore our export-ready wholesale portfolio. Built to tight dimensional tolerances, our cases provide maximum impact resistance for designer sunglasses, progressive ophthalmic lenses, and delicate reading eyewear.
Combining heritage leather craftsmanship with automated industrial stamping, cleanroom thermoforming, and rigorous multi-stage physical testing protocols.
We source cold-rolled SPCC steel sheets and high-tensile manganese spring plates for our hard-shell clamshell lines. Each unit undergoes a 50kg load-bearing compression test and 20,000-cycle mechanical hinge fatigue evaluations, eliminating lid sagging or clasp loosening in retail environments.
Every brand insignia is calibrated for zero ink bleed and abrasion resistance. Utilizing high-resolution micro-pad printing for curved cases, silk-screening for microfiber pouches, and heat debossing / foil stamping on genuine grain leather, backed by pre-production physical proof photo approval.
All raw leather substrates, synthetic polyurethane skins, water-based glues, and velvet interior linings are strictly tested for chemical migration. We guarantee low heavy-metal concentrations, zero hazardous phthalates, and DMF-free production runs meeting European and North American regulatory mandates.

Strategic analysis on supply chain decentralization, circular economy mandates, and smart-packaging integration within the global optical manufacturing industry.
Global optical retail brands are transitioning away from petroleum-heavy PVC. Demand is surging for waterborne PU, solvent-free plant-based skins (apple peel, mycelium), and 100% GRS-certified recycled ocean-bound plastics for structural inner frames.
High international container freight rates have propelled triangular foldable cases. These structures fold completely flat during transport, reducing shipping volume by up to 68% while delivering premium rigid protection when unfolded at retail.
Luxury eyewear OEMs are embedding sub-millimeter NFC tags under the leather lining. Patients tap their smartphone to access frame authenticity certificates, prescription lens specifications, and clinic re-ordering portals directly.
With increasing patient hygiene sensitivity, interior flocking linings are increasingly infused with non-leaching silver ion (Ag+) treatments, inhibiting 99.9% of bacterial colonization and fungal degradation inside dark enclosed case cavities.
Clear, unvarnished contractual and technical answers to streamline vendor qualification and mitigate sourcing risk.
For catalog models utilizing existing metal tooling with custom logo pad printing or hot foil debossing, our baseline MOQ begins at 1,000 units. For completely customized case geometries, specialized tooling molds, or unique Pantone-matched vegan leather textures, MOQs generally start at 3,000 units per run.
We deploy a zero-defect pre-production protocol: after receiving your vector artwork (AI, PDF, EPS), our tooling team generates digital die-cut schematics. We then manufacture physical proof prototypes and dispatch high-resolution studio proof photos or physical samples for your formal sign-off before mass stamping begins.
Yes. Low-grade glues emit off-gas volatile organic compounds (VOCs) that can induce crazing and delamination in premium Crizal or polycarbonate lens coatings. We exclusively utilize waterborne, solventless environmental adhesives and laboratory-inspected inert flocking liners to prevent any lens damage.
Absolutely. Over 60% of our production consists of complete dispensing bundles. We manufacture and color-coordinate your leather cases, matching 240 GSM silk-screened microfiber cleaning cloths, and 125ml customized private-label AR-safe cleaning spray kits, packaged into single ready-to-dispense retail boxes.
Our manufacturing plants operate under ISO 9001:2015 quality assurance and BSCI social compliance protocols. Product batches are tested via third-party laboratories (SGS, TÜV, Intertek) to conform with European REACH Regulation (EC) No 1907/2006, RoHS standards, and California Proposition 65 lead and phthalate limits.
Standard production lead time ranges from 18 to 25 calendar days post-sample approval. We routinely ship under Incoterms 2020 including FOB (Ningbo/Shanghai/Shenzhen), CIF, and turnkey DDP (Delivered Duty Paid) door-to-door delivery handling all customs clearance and tariffs for European and North American buyers.
