Why our Steluda Sunglasses are so special

Martzi Eyewear founder Davide, had the design/vision of the Steluda in his head for a while, and then began to sketch it out on paper. The sketch was then shown to the engineers who ended up making a prototype, and after some final meticulous changes, ended up with the final prototype.
The Steluda unisex frame comes in 3 different stunning acetate colours:
  1. Gloss black frame with gloss black temples that have a crystal clear layer in the inside, showing the strong and durable Italian steelwork.
  1. Havana, which really comes alive when the sun hits it, showing off the bright yellow and reddish-brown colours.
  1. Tortoise, classic acetate colour which will never go out of fashion.
Our Australian manufacturer for our Steluda line, sources a high quality thermoplastic acetate from renowned Italian acetate manufacturer Mazzucchelli.  It is completely biodegradable with a higher percentage of materials coming from natural sources.
Traditional milling machines and laser technology are used to get the precise cuts and curves for the Steluda frame. A four-stage grind and polish process that takes up to 120 hours (five days) to complete is then taken place.  The factory also assemble and polish each individual frame as part of their quality control process.   
Coming from one of Australia’s last remaining eyewear manufacturers, the Steluda frames go through a thorough 60 step process from start to completion, involving high-precision computerised machines, skilled hands, and also quality control at each individual step.
The factory uses machinery with cutting edge technology from France to shape the 100 percent eco-friendly acetate materials into the final product.
The frames are shaped using various widths of acetate sheets and then specialised machines compose them into required thicknesses to be cut into strips.  They are then shaped with more precision machinery.
The engineers then use mechanical and manual sequential heat treatment processes to customize the design, and then an automated tumbling phase to refine the frame.
The last step involves hand-smoothing, polishing and attaching the temples to the frames and finishing off with the insertion of the Zeiss Lens.

We are super excited to be approved to use the famous green and gold kangaroo logo on our Steluda Sunglasses.

Country of Origin Food Labelling

The Australian Made logo is a well-known and trusted country of origin certification. When you see this logo on a product, you can trust that it is authentically Australian, one of the world’s most familiar country of origin labels.

Because Australian manufacturing is regulated to ensure the highest quality standards, you know you are getting a high quality product that’s made to last the distance when you buy Australian Made. Stringent safety standards also mean that the Australian products you buy and the materials used to make them are monitored closely for compliance.

Buying Australian Made also means far fewer carbon miles and greenhouse gas emissions created in transporting your goods.



Australia has high safety and quality standards which are set in law (this means they have to be followed), so products that have been manufactured locally must meet these standards. Also, Australian products usually come with local customer support, so if you need any info about our Australian Made Sunnies, we are just a phone call away.


When you buy Australian products, the value you spend stays in Australia. This means that you are supporting Australian jobs. The company that produces the product can employ more Australians.

If more Australians have jobs, it means families are likely to have more money to do fun things like go on a holiday, go out for dinner or a movie, and pay for things like ballet classes, sporting club membership, as well as the weekly groceries and bills.

The company and employees will pay tax to the Government. This means there is more money to spend on things like hospitals, sporting facilities and schools.
