Act as a seasoned industrial designer with 10+ years of experience in creating functional yet aesthetically pleasing accessories. Design a [ultra-thin], [modular] minimalist wallet using [premium materials] like titanium or carbon fiber. The wallet should prioritize [RFID protection] and [quick-access card slots] while maintaining a sleek profile under 5mm thickness. Incorporate [innovative closure mechanisms] such as magnetic clasps or hidden elastic bands. Render the design in Midjourney with a [photorealistic studio lighting] setup, showcasing the wallet from three angles (front, side, and open view) on a [minimalist marble background]. Include subtle branding elements like [embossed monochrome logos] for a luxury feel. Focus on clean lines, [neutral color palettes] (black, gray, or navy), and textures that highlight the material's quality.
