MUSU, founded in 2021 by a brother and sister duo, is an eyewear brand that blurs the lines between style and elegance. Their debut collection of unisex sunglasses places product quality at the forefront, offering unique, timeless frames designed in the French Riviera and handcrafted in Italy. MUSU’s commitment to excellence is evident in their limited batch production, ensuring meticulous attention to detail, comfort, and environmental responsibility. Crafted by Mazuchelli since 1849, MUSUs feature plant-based Bioacetate, replacing plasticizers in ordinary acetate for biodegradable, recyclable frames. Musu frames are handcrafted in a family-run factory, in operation since 1950, located in the heart of the Cadore Valley.
