The IXXI cards are made of Synaps, a high-quality synthetic matte material. This material is 0.3mm thick and is tear-resistant, moisture-resistant, UV-resistant*, and therefore guarantees a long lifespan. In addition, an IXXI is completely free of toxic substances and 100% recyclable.
* However, it is possible that the print will fade over time if it is exposed to UV light frequently.
