Ultra-Thin Leather Card Holder "CARDRIDGE" for Left-Handers


Ultra-Slim Elegance: Just 1mm Thick

Discover the pinnacle of slim design with the "CARDRIDGE" by dünn, a Japanese brand celebrated for its ultra-thin leather goods. At an astonishing 1mm thickness (approximately 0.04 inches), this card holder redefines minimalism. Effortlessly slide it into your planner, wallet, or pocket for smart, unobtrusive storage.

Originally designed for right-hand access, we found ourselves longing for a left-handed version—and our collaboration brought it to life.

Designed for the Left-Handed

The CARDRIDGE features a left-side card slot, allowing left-handers to quickly and easily pull out their business cards. Its beautiful curve employs the "clothoid curve," often seen in the paths of roller coasters and highways, for a blend of aesthetic appeal and functionality.

Capable of holding about five standard business cards, its slim profile means no bulk in your planner, wallet, pouch, or pocket. It also serves wonderfully as a card case or money clip.

Supple, Ultra-Thin Genuine Leather

Crafted from leather as thin as 0.5mm by skilled Japanese artisans through meticulous hand-processed splitting, the CARDRIDGE offers the lightness of paper with the distinct soft touch of leather. We chose "Cobalt Blue" for its serene yet vibrant character.

Featuring both the CARDRIDGE and HIDARI logos embossed in an elegant double branding, this card holder stands out in both function and style.
