Black Coal is a metal cardholder designed using natural slate stone. Slate stone is formed deep underground over millions of years from clay, volcanic ash, and other finely structured rocks. Our product is minimalist, unique, and nature-inspired, and it is packaged using fully environmentally friendly materials.

Seif Design is an Estonian brand known for its globally unique stone-designed cardholders. Seif Design uses only fully recyclable materials for packaging and has transitioned its production processes to green energy sourced from solar panels. All Seif Design products are made in Estonia.

Kersti Kaljulaid (Estonian ex-president): “A wallet made from stone is as sustainable as it gets! A true counter to things with a short lifespan, hopefully lasting from father to son. I love it when things don’t break or wear away.”
