None

Glue is used on the edges of leather products to create a strong, durable bond that seals and protects the edges from moisture absorption and rot. Different types of adhesives like leather glue, contact cement, and epoxy are commonly used to ensure a permanent and flexible connection[4][2][3]. The application of glue on leather edges is crucial for repairing damaged items like shoes, belts, and bags, as well as for creating intricate leather crafts with a polished finish[5][1]. Proper preparation, alignment, and selection of the right adhesive are essential for achieving professional and long-lasting results when joining leather pieces together.
