Thanks for the comment!
You are very right that many brands use Mazzucchelli acetate in their glasses. The truth is that, even in a very reputable brand like Mazzucchelli, there are a variety of options in colour, type, quality of products that are available. In general, though, you will see that Mazzucchelli is the most highly regarded manufacturer of acetate in the world.
We are very proud to work directly with Mazzucchelli and hand pick the exact acetate we want to use in our frames. What you will notice with our frames (and any frame that uses high quality acetate) is that the acetate is sturdy, yet very comfortable, and does not warp easily over time.
In addition to using high quality acetate, our frames are also hand made and we use 5-barrel hinges . This makes the hinges (and the frame overall) more durable.
We're glad to hear you like the style of the frame. We hope you love them!
