A woman who chooses the Mad Fun model knows she is wearing a small work of art on her face, because the frames are colored by hand in seven phases by attentive artisans. The models can be appreciated for not only the texture of the various colors, but also for the fine carving in the steel that produces wood, netting and 3D cube effects. The hinge is also full of technology, of course, formed by seven joints in nylon and steel that avoid the loosening of the screw.
