A Our metal wallets are crafted using aerospace-grade 6061-T6 aluminum and 3K twill carbon fiber from Taiwan, both chosen for their exceptional balance of lightweight performance and structural strength.The aluminum surfaces undergo a Type II anodizing process, which increases surface hardness to industry standards. This treatment significantly improves scratch resistance, ensuring the wallet can withstand daily wear.

A We ensure the longevity of our elastic band and tension mechanism through a combination of advanced nylon material selection and rigorous durability testing. Each band is engineered using a high-density polyester fiber blended with latex strands, optimized to deliver both elasticity and structural resilience.This specific composition prevents premature loosening while maintaining consistent tension over time.
To validate real-world performance, our internal laboratory conducts 10,000+ stretch and fatigue cycle tests, simulating extended daily use.

A Our metal card holder is engineered to provide effective protection against 13.56MHz frequency scanning, which is commonly used by contactless credit cards, debit cards, and ID cards. In addition, our shielding performance has been tested in accordance with ISO/IEC 14443 standards, and also passed the RFID FCC ID testing to ensure reliable protection for widely used contactless cards.

A We incorporate an anti-scratch interior lining, which creates a soft buffer between the cards and the metal frame, reducing friction during insertion and removal. In addition, all internal edges are precisely finished using CNC chamfering, resulting in smooth, rounded corners that prevent abrasion or wear on the card surface.

A Gstar has strong in-house R&D capabilities to develop custom molds for unique metal wallet structures.We support a full development process, from initial 3D drawings and structural design to CNC prototyping, ensuring that your concept is accurately translated into a functional product.
