This is a fancy pair of frame with the adjustable length of the temples. Materials include the metal for the front and acetate for the rear part of the temples. At the front part of the temples, there is a metal cuboid connector which can be slid for stretching the length of the temples. Lenses shape in rectangle, a typical pair of men’s semi-rimless frame. Available in gunmetal, with the color-matching acetate temples, this is a little bit heavier frame, with total weight with lenses at 28-30 grams. The acetate temples help to achieve a firm grip on the ears.
