The Cose Backpack Buckle, 30mm in white, is a durable plastic buckle specifically designed to adjust and secure backpack straps, allowing you to regulate the length according to the wearer's height. It's built to withstand the weight and repeated use characteristic of a backpack, making it more robust than decorative buckles intended for occasional use. The white color is a versatile choice, easily matching backpacks of any style and fabric. It's an essential replacement accessory for repairing backpacks with broken buckles.
