Mere Marmor – Card Holder with RFID Blocking

About the Product

Mere Marmor – Card Holder with RFID Blocking by Seif Design is a metal card holder designed using natural marble. Marble typically forms when carbonate rocks are subjected to high temperature and pressure, often during tectonic movements. Depending on whether it has formed from limestone or dolomite, it consists of either calcite or dolomite, giving each piece its own subtle pattern and structure.

The result is a minimalist, unique, nature-inspired accessory that feels both technical and tactile. The card holder offers RFID blocking to help protect your cards against contactless theft, and it is packaged using fully environmentally friendly, recyclable materials.
