When launching or scaling an eyewear brand, one of the most critical operational decisions you will make is choosing your sourcing model.
Should you purchase in-stock, ready-to-ship wholesale frames directly from a manufacturer’s catalog? Or should you invest in custom OEM (Original Equipment Manufacturer) production to build unique designs from the ground up?
Both models have distinct advantages and drawbacks, and the right choice depends on your business stage, target audience, capital, and growth timeline.
As a professional eyewear manufacturer specializing in both wholesale supply and custom OEM/ODM solutions, we break down these two models to help you make an informed decision for your brand.
1. In-Stock Wholesale (Ready-to-Ship)
The in-stock wholesale model involves buying factory-designed frames that have already been manufactured and are sitting in the supplier’s warehouse.
The Pros:
- Zero Production Lead Time: Ready-to-ship frames are typically packaged and shipped within 3–7 business days, allowing you to stock your store or launch your collection almost instantly.
- Low Financial Entry Barrier: Because the factory has already paid for the mold development and raw materials, they can offer very low Minimum Order Quantities (MOQs)—often as low as 10 to 50 pairs for wholesale buying.
- Proven Styles: Factory stock collections are usually composed of classic shapes (like aviators, wayfarers, and round frames) that have a proven track record of sales success.
The Cons:
- Homogeneity (Lack of Exclusivity): Since these designs are open-mold and available to anyone, other brands might sell the exact same styles, leading to price wars and low brand differentiation.
- Limited Branding Options: While you can easily print or laser-engrave your logo on the temples, you cannot alter the frame shapes, colors, or structural details.
2. Custom OEM/ODM Manufacturing
The Custom OEM model is a collaborative manufacturing process where the factory builds frames based on your unique sketches, 3D CAD drawings, or custom material choices (such as choosing specific Italian Mazzucchelli acetate sheets).
The Pros:
- Total Brand Exclusivity: You own the design. No other brand in the world will have the same frame silhouettes, custom color combinations, or hinge details, allowing you to build strong brand equity.
- High Profit Margins: Unique, high-quality designer frames face less direct price competition, allowing you to position your brand in the premium-to-luxury segment and command retail prices of $150 to $300+.
- Custom Materials and Quality Control: You control every detail, from selecting biodegradable bio-acetate to using high-grade German OBE hinges or customized polarized lenses.
The Cons:
- High MOQs: Custom runs require the factory to purchase raw materials in bulk and set up dedicated tooling. MOQs typically range from 500 to 1,200 pairs per style.
- Long Production Timelines: The cycle of sketching, prototyping, mold making, curing materials, CNC milling, and hand-polishing takes time—usually 45 to 60 days from design approval to delivery.
- Upfront Development Cost: You will need to invest in mold/tooling fees and prototyping before mass production begins.

4. The Hybrid Strategy: The Smartest Way to Scale
Many successful eyewear brands do not choose just one model—they use a hybrid sourcing strategy to manage cash flow and reduce inventory risk while building brand value.
- Launch and Test (In-Stock + Custom Logo): Start by selecting a style of acetate, metal, PC, or TR90 frames from our in-stock catalogs. Use our 100-pair logo customization program to print your brand logo—this program requires a minimum of 100 pairs per single style, but you can select assorted colors of that same style to offer variety.
- Analyze Sales Data: After 2–3 months of sales, identify your “hero products”—the exact shapes and colors your customers love.
- Scale with Custom OEM: Transition those top-performing styles to custom OEM production. You can now tweak the designs to make them completely unique, buy materials in larger bulk to lower your unit cost, and maximize your profit margins.
