Our Rotterdam Sand Tortoise – a glasses highlight in a modern retro look, which not only convinces with its style, but also scores with the first-class choice of materials! The brown-beige patterned, large frame is made of high-quality bio-acetate and impresses visually with its square shape and oversized lenses, which are reminiscent of the extravagant look from the 70s. Looking for an absolute glasses must-have? Then our Rotterdam Sand Tortoise is the perfect model for you!
