The Cose Metal Buckle with Rectangular Slider, 30mm in silver, reference 754103, is a rectangular frame-shaped metal buckle used to adjust the length of straps and belts without a locking function, only a sliding mechanism. This alternative reference corresponds to a different buckle model within the same 30mm silver range, maintaining the same robustness. It is an essential accessory for those who make bags, backpacks, and adjustable belts with a more robust finish than conventional plastic.
