NATURAL ACETATES All the acetates Etnia Barcelona works with are produced in Italy with our partner Mazzucchelli. Acetate, unlike injection, is a 100% natural and malleable material made from cotton. FLEX HINGE This model incorporates the flex hinge; the flexo adapts perfectly to the face to provide superior comfort and quality. COLOUR Etnia Barcelona carefully selects and develops all the colours in its collections, always based on art and fashion trends. BARBERINI LENSES Assembled with top quality Barberini mineral crystal lenses. They enable perfect vision. This is one of Etnia Barcelona's main objectives, and so we work with HD, photochromatic, anti-scratch, oleophobic, and polarised filters. DETAILS "Devil is in details": every part of the frame counts, and that's why we attach enormous importance to application, shape and material conforming the product.
