That is exactly where classic frames go wrong. A browline - the clubmaster style silhouette - is harder to build than a full-rim frame. The top is an acetate brow bar, the bottom is a metal rim, and everything depends on how those two materials meet. Get that junction wrong and the whole frame sags: gaps between acetate and metal, plating that mottles after two months of wear, nose pads that drift out of alignment within days. End customers cannot name the problem. They just decide the sunglasses are not worth the price.
This model was built to answer those three failures, one by one.
The Shape: An Arched Brow and a Squarer Lens
The browline sunglasses for men have sold since the 1950s for one structural reason: the heavy brow pulls attention to the upper half of the face while the metal rim nearly disappears. Square faces, round faces - both work.
On this model the brow bar carries a gentle upward arc instead of the old flat line, paired with a squarer lens shape. The reason is commercial. Plenty of vintage sunglasses for men fail at this exact point: a flat brow with rounded lenses reads as costume on anyone under thirty. The current combination keeps the retro reference but looks current, which widens the age range of the end customer your buyers can sell to.
The rivets at the frame corners are working parts. They anchor the joint between the acetate brow and the metal rim - the exact spot where browline frames loosen first. That they also happen to be the most recognized visual signature of this frame style makes them a feature worth keeping at any price point.
Materials: Each Part Doing Its Own Job
The brow bar uses Mazzucchelli acetate Sheet quality is obvious the moment you hold the frame: good acetate has depth after polishing, and this black marble version shifts from solid black to a moving texture when the light angle changes. Recycled sheet sits flat and dull under the same light.
The rims and temples are 1.3mm stainless steel. The thickness was settled by trade-off. Thinner steel loses its crispness; thicker steel presses on the nose after half a day. At 1.3mm, stainless also outlasts alloy in sweat - and the sweat-plus-sea-air mix of a beach holiday is precisely the environment that punishes weak metal.
Three Processes Decide the Price Gap
Hand polishing: Acetate parts come off the machine matte; the shine is ground in by hand, a minimum of three passes per batch. The fastest check is the inside of the brow bar - run a fingertip along it. Corners that never touch a display photo are exactly where cheap polishing leaves its burrs.
IP plating: Whether metal parts keep their color depends on the plating shop. Small shops lay thin coats with weak adhesion; two weeks of perspiration and the surface mottles. Our metal parts go to an established plating factory running IP plating. One counterintuitive point from years of export orders: gunmetal hides wear better than bright silver. Scratches show on bright silver almost immediately; gunmetal absorbs them. For beach and resort channels we recommend gunmetal as the starting color.
Hinges: This model uses a barrel hinge with screw construction, sourced from OBE, comotec, or Kanghua depending on the order. Spring hinges have their place - higher-stress frames and larger sizes. A barrel hinge built on branded hardware covers the full wearing life of a frame at this price point, and the cost difference lands in your quotation. Some suppliers fit spring hinges to everything and let the savings hide elsewhere. Ask where.
How It Wears: 30.7 Grams and an Adjustable Nose Pad
Total weight is 30.7 grams - light for a combined acetate-and-metal sunglassesbuild, comfortable across a full day outdoors.
The nose pads are adjustable, set on metal arms. The practical difference matters most at retail: one-piece acetate nose pads either fit or they do not; adjustable pads take a salesperson ten seconds to match a customer's bridge. For retail chains, that means fewer fit complaints reaching your returns desk. For gift and promotional programs, where the recipient's face is unknown, an adjustable pad absorbs the sizing guesswork before it becomes an exchange.

Sampling: About 20 days after the sample fee arrives. The fee returns in full with your bulk order - effectively, you pay one courier bill for the sample.
Logo: Metal-core engraving inside acetate temples, metal badge inlay, silk printing, hot stamping. Process photos are on this page; if two options look close, we mail physical samples for a side-by-side comparison.
Lenses: The default build is 2.0mm nylon with UV400. Polarized or gradient tints are available; the price difference and added lead time appear as separate lines on the quotation, confirmed at the sampling stage.
Packaging: Standard export packing is polybag, white box, carton. Branded builds - cleaning cloth, pouch, leather case, hard box - are available through packaging suppliers we have used for years, at rates below sourcing them separately.
To extend this shape into a small series - different lens forms, brow arc adjustments, new colorways - all are routine development work for our team. Custom sunglasses programs at this scale do not need a design department on your end; a reference image is enough to start.
How an Order Runs

Frequently Asked Questions
Q: Do you charge for samples?
A: Yes, with the fee returned in full against a bulk order. Allow about 20 days. For urgent timelines, tell us when you send the request and we hold a production slot.
Q: What if the metal parts lose their color?
A: IP plating through an established plating shop covers normal perspiration conditions across the standard after-sales life of EU and US retail. If your market or your standard demands more, state it when ordering - we run the additional colorfastness testing against your specification, quoted as its own line.
Q: Are the lenses polarized?
A: The standard build is 2.0mm nylon with UV400. Polarized and gradient tints are available on request, with the price difference and extra lead time listed on the quotation and locked at sampling.
Q: Can the arched brow be changed to a flat brow?
A: Yes - a shape adjustment at this level costs little or nothing since no new mold is involved. One consideration from previous orders: a flat brow suits fewer face shapes, and younger markets tend to respond better to the arched version. If your market spans both, produce one sample of each and let the sell-through decide.
Q: How do we start?
A: Email Leah@leeyewear.com with reference images or your design, quantity, and destination market. A quotation with lead time comes back the same day.
