We work premium-quality cellulose acetate, containing up to 80% of cotton, milled with the latest Japanese CNC machines at 5 axes.
The lenses are cut by an high-precision automated machine. The polishing is done with the four stages process of tumbling lasting over 168 hours, and then brushing and finishing are done by hand.
Therefore, the production cost of acetate sunglasses is more, and the construction period will be longer.
