The Nano card holder is the slimmest, lightweight card holder in this collection and has been handmade with a high-quality alternative to leather. Made from non-food grade corn, the material contains more than 30% plant content. The corn is from a renewable source, and the final material is 3 x more environmentally friendly than animal leather. The surface layer of PU provides water, stain and scratch resistance. Inside, the woven lining has been made using 100% recycled plastic bottles. It is soft and strong like polyester, but unlike virgin polyester, recycled PET fabric has a significantly lower impact on the environment. It uses 94% less water, 60% less energy and 32% less CO2 to manufacture. Features: 1 single pocket for cards. Comfortably holds 8-10 cards with RFID Protection Dimensions: 10cm (H) × 8cm (W) × 0.2cm (D) **About the maker.** The foundations of Watson and Wolfe are built on four values, which are woven into everything they do and into every decision they make.
