Flight Options binder covers are another outstanding example of how solid aluminum binder covers can be distinctive, and sophisticated. These great looking binder covers are solid anodized aluminum with radius corners and a piano hinged spine. The decoration is screened artwork, and the interior is panel lined in a black faux leather. This is one of three prototypes that we made. The other two included: One with a black faux leather quarterbind spine, and the other with a frosted acrylic front cover with a piano hinged spine. Very sophisticated and distinctive aluminum binder covers.
