Because of its durability and versatility, all Adrian Mustelin Spectacles' frames are made of acetate. The Limited Edition spectacles are produced from unique, out-of-stock acetate from between the 1960's and 1980's, a very small amount of which was salvaged from an old warehouse. Like all Adrian Mustelin Spectacles' models, the Limited Edition shades are singularly handcrafted by traditional optician methods.
Due to the diminishing amount of their distinctive raw material, each pair of these vintage shades is numbered.
