4Prefer a truly slim carry? BillFold 4.1 is built for minimalists who want less card storage and an even slimmer profile—without compromising tracking or data protection. Handcrafted in Europe from Italian full-grain vegetable-tanned leather, it slips easily into front pockets while keeping essentials organized and secure.

A refined, hidden AirTag pocket sits inside the wallet and is secured with a Torx-screw closure, helping deter quick removal and keeping the tracker discreet. For privacy, we integrate a certified RFID-blocking layer by Shieldex® (Germany)—a silver-based electromagnetic shielding textile that protects contactless cards from unauthorized scans while staying flexible and durable.

Capacity (slim by design)

• 1 large compartment with pull-tab for up to 7 cards
• 1 quick-access  pocket for your most-used card
• 4 card slots inside the bill section (each holds 1–3 cards)
• Full-length bill pocket fits: U.S. Dollars, Euros, Canadian Dollars, Australian Dollars, Japanese Yen, Singapore Dollars, Hong Kong Dollars, and New Taiwan Dollars

Why you’ll love it

• Slim profile for front-pocket comfort
• Hidden, Torx-secured AirTag slot for discreet, reliable tracking
• Shieldex® RFID-blocking fabric helps protect payment and ID cards
• Italian vegetable-tanned leather that develops a rich patina
• Handcrafted in Europe with precise edge finishing and durable stitching

*This wallet is compatible with AirTag. You can buy an AirTag on apple.com

Premium Italian Leather

Sourced from an old Italian tannery with a rich history, located in the Tuscany region.

This vegetable-tanned leather offers a pleasant, soft tactile experience with a beautiful smell and develops a rich patina over time, reflecting your unique character.

During production, only natural tannins are used, making it free from harmful chemicals. Additionally, much less water is used compared to the production of usual chrome-tanned leather, making it an environmentally friendly choice among other leather types.
