ZVNDER was founded in 2017 by designer Nina Fabert after material studies and research on the processing of tinder fungus (Fomes fomentarius). The company material, FUNGISKIN, is cut from a single mushroom body and varies in size, color, and shape accordingly. It cannot be produced in large sheets. Because it is an entirely natural product, FUNGISKIN shows traces of use over time and is sensitive to moisture and dirt. According to the company, FUNGISKIN feels soft due to its high air content, which also gives it insulating properties.
