This sleek, ultra-thin card holder features premium textured PU leather in a sophisticated purple hue (labeled '紫藤色'—Wisteria Purple), designed for minimalist smartphone users. The front side includes a single horizontal card slot with precise stitching and rounded corners for smooth insertion/removal, while the reverse side integrates a precisely cut oval MagSafe-compatible mounting area—enabling seamless attachment to iPhone 12/13/14/15 series with magnetic alignment. Its slim profile (approx. 3–4mm thick) adds no bulk, making it ideal for pocket or bag carry without compromising phone functionality. The fine grain texture offers subtle grip and durability, while reinforced edges prevent fraying. Perfect for daily urban commuting, business casual settings, or travel where minimalism and utility are prioritized. Compatible with most standard credit cards, IDs, and transit passes; the magnetic backing ensures secure attachment even during movement. Not a branded product—designed as a generic functional accessory with clean, modern aesthetics.
