To achieve flawless replication of handcrafted Hermès bags, the hardware materials and installation procedures must fully conform to genuine product standards. Shebag consistently applies authentic craftsmanship specifications to standardize every operational procedure in its production workshops.

The base studs are made of solid brass alloy with surfaces plated with precious metals including gold, palladium and ruthenium. Boasting superior hardness and ductility compared to zinc alloy, such studs feature excellent wear resistance and structural stability, and will develop a subtle elegant patina through natural oxidation over long-term use. Structurally speaking, these integrated threadless studs differ from conventional screws, consisting of stud heads, shafts and tails. Four such studs are installed at the four bottom corners of Birkin and Kelly bags to support the bag body and mitigate leather abrasion effectively.

Artisans first manually mark accurate positions at four corners and drill precision holes with dedicated punches. The hole diameter is slightly smaller than that of the stud shaft to enable interference fit, ensuring all holes are vertically aligned and evenly spaced without deviation.

Stud shafts are inserted inward from the outer leather layer through the base pad and inner leather, with brass gaskets attached on the reverse side to disperse pressure and prevent leather cracking. Excess stud tails are trimmed to a reserved length of approximately 1.5 to 2 millimeters, which are then gently struck vertically with round hammers and curved punches to achieve preliminary flattening and tight fitting against the gaskets.

As the core anti-counterfeiting procedure of Perlage forming, artisans apply even circular striking force with concave curved punches while rotating the tools steadily, forging flattened stud tails into smooth pearl-shaped mushroom ends. The finished studs can fully cover the attached gaskets with seamless and smooth surfaces, forming an integrated fastening structure that tightly locks onto leather materials without loosening or falling off permanently. Visible handcrafted traces including natural concentric hammer marks, subtle surface undulations and mild color gradients can be observed on stud heads, which stand in sharp contrast to overly polished machine-finished surfaces and serve as core identification features of genuine products.

Outer edges of stud heads are rounded and manually polished to eliminate sharp corners, with uniform metal plating that turns into mild antique bronze tone after long-term oxidation rather than coarse glaring luster seen on inferior hardware.

Genuine Hermès hardware presents distinct practical characteristics. Stud heads are slightly sunk into leather with subtle natural indentations on surrounding leather formed by manual staking tension instead of lying flat on the surface. The overall integrated structure features no screw holes or welding seams, matched with naturally textured pearl-shaped stud tails and mild metallic luster. All four studs maintain uniform height, symmetrical layout and perfect vertical installation angles.

Inferior counterfeit products generally have obvious flaws in production execution. Their studs are simply attached flat against leather without sinking effect and tend to detach easily. Some low-grade replicas adopt screw fastening structures which are prone to loosening and rust leakage. Mass machine polishing leads to overly sleek mirror-like surfaces lacking authentic hand hammer textures and presenting rigid sensory effects. In terms of raw materials, inferior zinc alloy studs are susceptible to deformation, plating peeling and uneven dark oxidation.

This mature craftsmanship system delivers remarkable practical value and product advantages. The combination of brass raw materials and professional Perlage forming realizes firm cold-bonding between studs and leather, guaranteeing stable load-bearing performance and long-term structural reliability. Besides, raised base studs effectively separate the bag body from contact surfaces, greatly reducing direct friction on leather and extending the overall service life of finished bags.
