Seif Design
Black Coal - Card Holder with RFID Blocking
€46,99 EUR
Unit price perMinimalist Design Inspired by Natural Stone
Black Coal is a unique metal card holder designed with natural slate stone, combining durability with a distinctive natural appearance. Slate forms deep underground over millions of years from compressed clay and volcanic ash, giving each piece its own subtle texture and character.
The card holder reflects a minimalist design approach — compact, practical and built for everyday use. Its solid construction protects your cards while maintaining a slim profile suitable for carrying in a pocket.
Equipped with RFID blocking protection, the card holder helps shield contactless cards from unauthorized scanning, offering additional security for modern everyday carry.
Sustainable Craftsmanship
Black Coal is created by Seif Design, an Estonian brand known for its globally unique stone-designed card holders. The company focuses on sustainable production and environmentally responsible materials.
All Seif Design products are manufactured in Estonia, and the brand has transitioned its production processes to green energy generated by solar panels. Packaging materials are fully recyclable, supporting environmentally conscious production.
Former Estonian president Kersti Kaljulaid described the product:
“A wallet made from stone is as sustainable as it gets — a true counter to things with a short lifespan.”
