From JMM's limited-edition series Éditions Pliables, with a compact, pocketable folding construction. They're an ode to classic sixties styles, handcrafted in Japan from gold-tone Armorlite titanium that's ultra lightweight and resilient. Custom tension-secured hinges ensure they'll stay firm for years to come.

The beauty of this product is the folding mechanism, which took over two years to perfect.
