Highly intricate multi-dimensional laser etching applied to the titanium, with high quality enamel insets. 100% pure titanium plated in 12k silver, 18k gold, or 24k gold combined with Japanese cotton-based acetate temple tips and a hidden spring hinge. Individually numbered and handmade in Japan from the world’s finest artisanal craftsmen.
