- Collection:SHEET TITANIUM - A combination of 100% pure titanium and beta-titanium. This male style is the true classic of the collection, an elegant and slim titanium frame suitable for medium-sized faces. Super Cell provides a pure and minimalist expression. The simplified design is paired with seven different color variations ranging from subdued Mat Tuxedo Blue to a more powerful Mat Blue Night/Mat True Red combination, which changes the expression of the frame altogether.
