This ultra-thin metal card holder is made of aerospace-grade aluminum alloy or stainless steel, with an anodized or sandblasted finish for a matte texture. Its extremely thin profile allows it to easily fit into a ont pocket. An internal RFID anti-magnetic layer effectively protects card information. The card holder uses a spring or button mechanism to eject cards and holds 6-15 cards. Some models include a metal wallet clip or elastic strap. In terms of manufacturing process, the metal casing is precision-machined using CNC, with chamfered edges to prevent cuts; the pop-out mechanism uses a stainless steel spring for long lifespan. Suitable for minimalist men, business professionals, or tech enthusiasts, it’s lightweight, sturdy, and modern, a stylish alternative to traditional leather wallets.
