The JoBolt Must Süsi is a metal card holder unlike anything else on the market. Its surface is crafted using natural slate — a stone formed deep underground over millions of years from clay, volcanic ash, and fine-grained rock. The result is a card holder that is genuinely one of a kind: minimalist, nature-inspired, and quietly extraordinary.
Designed and made in Estonia, the Must Süsi holds up to 12 cards and features built-in RFID blocking to protect your contactless cards from electronic theft. Available in two versions — with or without a money clip — so you can choose the setup that works best for you.
“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.”
— Kersti Kaljulaid, former President of Estonia
Every element of the production process has been designed with sustainability in mind: packaging is fully recyclable, and production runs on green energy from solar panels. This is a card holder you can feel good about carrying in 2026 and beyond.
