Vision Onyx

Crafted by Mazuchelli since 1849, MUSUs feature plant-based Bioacetate, replacing plasticizers in ordinary acetate for biodegradable, recyclable frames. Tests confirm its enhanced strength and eco-friendliness.

Musu frames are handcrafted in a family-run factory, in operation since 1950, located in the heart of the Cadore Valley. To make your MUSUs, expert craftsmen go through more than 50 production steps, from sourcing bioacetate sheets to the final polishing touch.

Since quality is our top priority, we meticulously produce exclusive batches of Musu sunglasses, limited to a maximum of 50 pairs per color. Each pair bears a distinguished and individually assigned number, engraved within the temple, ranging from 1 to 50.

Keep your MUSUs safe in their case when not in use. Use the RPET cloth for quick cleaning or get a cleaning product and microfiber cloth for deeper care. Don't wear them on your head and avoid hot places to maintain their fit and quality.

The storage case is made from recycled vegan leather, or more precisely 60% leather fibre (scrap and waste leather fibre mainly from the unwanted by-products of industrial glove manufacturers), 30% polymer (a natural binder from rubber trees) and 10% coating (water-based polyurethane coating).

Our cleaning fabric is made of 100% PET from recycled plastic bottles.
