Walter Wallet sustainably produces their wallets in the Netherlands via a highly efficient injection-molding system that minimizes energy usage. Their vision was to create a wallet that helps you find the card you need quickly and easily. Walter Wallet's patented stack and slide system is invisible from the outside, which means the mechanism is protected inside the casing. The durability from the materials used in the wallets protects your cards from getting bent or damaged. Walter Wallet designed a wallet that’s precisely 15.4 mm thick to hold 7 cards or fewer. Walter Wallets are thin, lightweight, and elegantly assembled to be used on a regular basis.
