Invicta's pricing seems to be competitive with an additional feature [spring hinge]. Both are fiberglass. The Tsukayu fit and finish was excellent and there OEM paint match was perfect.
Invicta's mount system is identically designed except Tsukayu's rigid hangers were chromed.
On Invicta's product you probably can't go wrong, but their service is an unknown to me. Tsukayu's bag order took about 7 weeks [shipped from Japan in a fiberglass crate] including OEM matching paint.
