earth Wallet is a compact card wallet made from full-grain leather. It is designed to hold three cards and to be used daily. The wallet has no moving parts, electronics, or additional components. Its function is limited to carrying essential physical cards.

Leather has been used for tools and everyday objects for thousands of years. It is valued for durability, flexibility, and resistance to wear. earth Wallet applies this material in a reduced form, using a simple construction that prioritizes function over variation.

Not all objects have been replaced by digital devices. Identification cards, driving licences, and other official documents continue to exist in physical form and often cannot be displayed digitally. Electronic devices also rely on power and software. earth Wallet operates independently of these constraints and remains usable at all times.

The wallet is produced using vegetable-tanned leather. This tanning method preserves the natural structure of the material and avoids synthetic tanning agents. Through regular use, the surface changes gradually. Exposure to light, friction, and handling causes the leather to darken and soften. These changes are cumulative and permanent, resulting in visible patina. Each wallet develops differently depending on how it is used.

Only full-grain leather is used. Full-grain leather retains the complete surface layer of the hide and is considered the highest leather grade. The leather used for earth Wallet is sourced and processed in Switzerland. It is tanned with plant-based extracts derived from wood, bark, and fruit. The material is a byproduct of existing industries, reducing the need for additional resource extraction.

The design of earth Wallet follows principles associated with classical modernism and the Bauhaus tradition. These principles emphasize clarity, restraint, and the relationship between form and function. Historically, leather accessories have been used in industrial design as functional complements to technical products. earth Wallet continues this approach through minimal form and material consistency.

The construction consists of four layers of leather. These layers are stitched together to create three compartments: one central compartment and one compartment on each side. The stitching is visible and structural. No additional lining or reinforcement is used.

The result is a slim wallet intended for long-term use. The object changes over time but remains functionally consistent.
