The 40x10cm C9754C inner tubular wallet closure is a large metal frame designed to provide a rigid structure and a rectangular opening to large bags. Made of lightweight and resistant steel, measuring 40 cm in length and 10 cm in width, it inserts invisibly into the upper hems of the bag. Its lateral articulation mechanism allows the bag to be opened and closed stably, maintaining the shape of the piece and preventing deformation from the weight of the interior objects. It is fantastic for the handcrafted making of travel bags, weekend bags, beach bags and briefcases.
